AERODYNAMIC MOMENTS CONTROL OF WING MODEL USING PLASMA JET

为考察火花放电等离子体射流控制机翼气动力矩的效果,在NACA0021平直机翼模型上安装火花放电等离子体射流发生器,通过改变射流发生器安装位置、射流角度及加载电参数,研究其控制机翼模型气动力矩的性能及机理。在NACA0021机翼模型近前缘处,布置2个火花放电等离子体射流发生器,采用气动力测量技术,在来流风速为20 m/s时测得,攻角-4°~10°时,滚转力矩系数最大减小了0.0024,攻角为12°~16°时,滚转力矩系数最大增加了0.0021;偏航力矩系数最大减小了0.00097。实验研究结果表明:等离子体射流可改变机翼模型横航向气动力矩,并可通过改变射流角度和加载电压频率调节等离子体射流控制横向气动力矩的效果。To investigate the control effect of Spark Discharge Plasma Jets(SPJs) on the aerodynamic moments of a wing, SPJ generators were used for active flow control experimental study on an NACA0021 straight wing model. The location of SPJ generators along the chord of the airfoil, the jet flow direction relative to the chord, and the driving voltage parameters were changed to research the control effect and mechanism of SPJ generators on the aerodynamic moments of a wing model. The aerodynamic moments were measured with a six-component balance at a wind speed of 20 m/s. Two SPJ generators, arranged near the leading edge, reduced the rolling moment coefficient by a maximum of 0.0024 for angles of attack-4°~10°, but increased the rolling moment coefficient by a maximum of 0.0021 for angles of attack 12°~16°. The yaw moment coefficient was reduced by a maximum of 0.00097. The results show that aerodynamic moments control of wings can be realized using SPJs. The control effect of SPJs on the aerodynamic moments is changeable by adjusting the driving voltage frequency and the jet flow direction relative to the chord.航空科学基金项目(20141368007);; 福建省自然科学基金项目(2010J01014

STUDY ON EXPERIMENTS FOR SUPPRESSING WINGTIP VORTICES WITH PLASMA

该文对利用dbd等离子体注入能量抑制翼尖涡进行了风洞试验研究。通过采用PIV粒子成像测速技术测量了三种不同结构的等离子体激励器影响下的后掠翼下游的尾涡流场,并结合矩形机翼在等离子作用前后的气动力变化,来判断等离子体抑制翼尖涡的效果。试验结果表明:在机翼翼梢的上下表面处布置等离子体激励器,通过等离子体产生的定向诱导气流形成诱导涡对流场注入能量,可以有效地延缓翼梢上翼面流动分离,抑制翼尖涡,增加升力,提高升阻比。在翼尖处流动分离较小时,等离子体抑制翼尖涡强度的效果明显;在大攻角下仍具有一定的作用;其效果与等离子体发生器的结构有关。因此,通过优化等离子体激励器结构,选择合适的等离子体激励器在翼梢表面的安放位置,可以更好地提高抑制翼尖涡的效果。The wind tunnel experiment on suppressing wingtip vortices(WTV) through adding energy with DBD plasma has been conducted in the paper.The WTV flow field of a swept wing has been visualized by PIV and the aerodynamic forces of a rectangular wing have been measured,in the condition of using three different kinds of plasma actuators respectively.The results show that the WTV may be suppressed and the separation on the upper wingtip surface may be delayed because the energy of the vortex induced by the plasma(VIP) is added into the flow field,which increases the lift and the ratio of lift to drag at a small angle of attack(AOA) effectively.Even at large AOA,the effect of plasma still appears.The effects are related to the structures of the plasma actuators.It can be obtain better results to suppress the WTV through optimizing the design of the plasma actuators and choosing the appropriate placement to install the actuators on wingtip surface.福建省自然科学基金项目(A1010014

Photosynthetic capacity of three common species of macroalgae and the application in coral aquarium

利用水下饱和脉冲调制叶绿素荧光仪(dIVIng-PAM)测定了珊瑚养殖水处理中3种常见大型海藻石莼(ulVA lACTuCA)、条浒苔(EnTErOMOrPHA ClATHrATA)和羽状蕨藻(CAulErPA MEXICAnA)光能转化效率(fV/fM),快速光曲线(rlC)相关参数和非光化学淬灭(nPQ)。结果表明:石莼和条浒苔的fV/fM分别为0.808±0.004和0.816±0.009,显著高于羽状蕨藻。最大相对电子传递速率rETrMAX(17.52±2.92和19.59±4.43μMOl E·M-2·S-1)、半饱和光强Ik(53.41±8.18和59.71±13.52μMOl PHOTOnS·M-2·S-1)也明显高于羽状蕨藻(rETrMAX和Ik分别为13.72±5.41μMOl E·M-2·S-1和32.67±14.06μMOl PHOTOnS·M-2·S-1),表明石莼和条浒苔有着比羽状蕨藻更高的光合能力和对强光的耐受能力,光保护能力更强;羽状蕨藻较高的rlC初始斜率α表明其在弱光下拥有更强的光捕获能力,弱光下光合效率更高;随光照的增强(0~373μMOl PHOTOnS·M-2·S-1),羽状蕨藻nPQ的增幅有限(0~0.2),最大值仅为条浒苔和石莼的38.1%和62.5%,表明这种藻类更容易受到强光的抑制。因此,在珊瑚养殖的水处理中,可以根据不同的光照选择适宜的藻种或藻种组合并根据光梯度进行布局,反之也可以根据藻种来选择合适的光源,以达到最佳的处理效率。This study investigated the difference of photosynthetic capacity in three macroalgae species( Ulva lactuca,Enteromorpha clathrata,and Caulerpa mexicana) commonly used for nutrient removal in coral aquariums.The photochemical efficiency( Fv/Fm),parameters relevant to rapid light curve( RLC) and non-photochemical quenching( NPQ) in the macroalgae were measured by underwater saturation pulse modulated chlorophyll fluorometer( Diving-PAM).The results showed that Fv/Fmwas 0.808 ± 0.004 for U.lactuca and 0.816 ± 0.009 for E.clathrata,which were higher than that for C.mexicana.Higher maximum relative electron transfer rates( rETRmax)( 17.52 ±2.92 and 19.59 ±4.43 μmol e·m- 2·s- 1) and half-starved value of light intensities( Ik)( 53.41 ±8.18 and 59.71 ±13.52 μmol photons·m- 2·s- 1) were observed in U.lactuca and E.clathrata than that in C.mexicana( 13.72 ± 5.41 μmol e·m- 2·s- 1for rETRmaxand 32.67 ± 14.06 μmol photons·m- 2·s- 1for Ik),indicating that U.lactuca and E.clathrata have stronger photosynthetic capacities,photo-protection capacities and tolerance to higher intense light than C.mexicana.A significantly lower RLC initial slope α in C.mexicana implied that this algal species has a higher photosynthetic capacity under weak light condition.With increasing the light intensity( 0- 373 μmol photons·m- 2·s- 1),however,C.mexicana had a limited increase of NPQ( 0- 0.2),the maximum of which was equivalent to 38.1% of that in U.lactuca and 62.5% of that in E.clathrata.These results indicate that the photosynthesis of E.clathrata may be more easily limited by intense light.Our study suggests that the selection of algal species for nutrient removal in a coral aquarium should be adapted to the light intensity.Single species or the combination of different species of macroalgae can be selected according to the illumination of the coral aquarium in order to maximize the efficiency of nutrient removal.国家海洋局第三海洋研究所基本科研业务项目(海三科2011033); 厦门海洋研究开发院共建项目; 海洋公益性行业科研项目(201105012)资

为探究等离子体合成射流对三维模型的流动控制效果和机理,在中等展弦比飞翼布局模型前缘布置等离子体合成射流激励器开展低速风洞实验研究。通过六分量天平测力,考察沿弦向、展向不同分布位置的等离子体合成射流对飞翼模型气动力和气动力矩的作用;采用PIV(Particle Image Velocimetry,粒子图像测速)测量模型表面流场分布,研究等离子体合成射流流动控制机理。结果表明:在飞翼模型单侧布置等离子体合成射流,能够有效改善其气动特性,并能产生附加的滚转力矩,滚转力矩系数变化量最高达到0.009;在飞翼模型左右弦布置等离子体合成射流,能显著增强飞翼模型横向稳定性,滚转力矩系数波动范围减小66.7%。沿弦向,等离子体合成射流位置离前缘越近,控制效果越好,距前缘0mm的激励器控制效果最好;沿展向,布置的等离子体合成射流越多,对模型的升力特性改善作用越明显,布置方式以均布为优。在失速迎角前后,等离子体合成射流的流动控制机理不同:在小迎角下,等离子体合成射流在前缘起到了使转捩提前的作用;在失速迎角附近,则加速了分离区的流动、减小了分离区厚度。国家自然科学基金项目(51707169)中航工业创新基金产学研项目(cxy2013XD28)福建自然科学基金项目(2019J01042)厦门大学校长基金项目(20720170057

The relationship between the profile of mood states and the emotional perspiration

Two kinds of psychological test with questionnaire, the profile of mood state (POMS) and the Tokyo university method of egogram (TEG), ｗere carried out in twenty-nine normal students aged from 18 to 25 years. In the same subjects, the palmar perspiration induced by mental and physical stimulation were concurrently measured using the Kenz-Perspiro OSS-100 (Suzuken Corp.), The POMS test includes six scales of mood state; tention-anxiety (T-A), depression-dejection (D), anger hostility (A-H), vigor (Ⅴ), fatigue (F) and confusion (C). The TEG test includes five scales indicating the ego states, critical parent (CP), nuturing parent (NP), adult (A), free child (FC) and adapted child (AC). The relationship between the psychological tests of POMS and the TEG, and the emotional sweating phenomena were summarized as follows ; 1) The T-A, D and A-H scales in the POMS test were significantly correlated with CP scale in the TEG test. The V scale in the POMS test was positively correlated with the FC scale in the TEG test and negatively correlated with the AC scale in the TEG test. 2) The palmar perspiration induced by jigsaw puzzle showed a very high correlation with the A-H scales in the POMS test. The correlation coefficient was 0.66 (p<0.01). 3) A negative correlation was observed between the palmar perspiration rate and the V scale in the POMS test. 4) On the basis of the POMS scales, nomal students were devided into two mood states groups ; stable and unstable groups. The palmar perspiration was more remarkable in the unstable group than in the stable group.Article紀要 21: 11-17(1996)departmental bulletin pape

皮膚電位反応を用いた情動反応評価に関する基礎的検討

We have measured the skin potential response (SPR) in thirteen normal students aged mean 20 years under the mental stimulations of the Hasegawa's dementia scale-revised (HDS-R). The SPR signals were detected by the bipolar electrodes placed on the ventral side of the middle finger of left hand and the middle point of left forearm. The using HDS-R involved the nine kinds of stimulation ; age, orientation date, orientation place, repeating 3 words, serial subtraction, digits backward, recalling of 3 words, recalling 5 objects, generating Vegetables. The results of this experiments were summarized as follows ; 1 ) The average values of the magnitude and latency of the SPR induced by the HDS-R were　4.3±3.0mV and 1.6±0.9 sec respectively. and so the large individual variations were contained in its SPR magnitude. 2) The two mental stimulations of serial subtraction and recalling 5 objects in nine test of the HDS-R caused the biggest response of the SPR magnitude, and this tendency of the SPR was coincident with it of the emotional sweating for the HDS-R.Article紀要 22: 105-112(1997)departmental bulletin pape
