Macro-Surface Modifications of Subsonic Flow on Airplane Winglets

Airplane winglets are used to improve the efficiency and noise or vibrations of fixed-wing aircraft. In this paper, the surface modification involves alteration on surface’s features to improve the performance of a product is being conducted. The surface modification was implemented on winglet surface in order to investigate whether the modified winglets provide better performance or not compared to the conventional wing designs. Two types of models were used which is a rectangular plane and airplane winglet, each with different types of surface modifications. For rectangular plane, four surfaces were introduced which is smooth plane, dimpled plane, riveted plane and extruded rivet plane. As for winglets, three surfaces were used which is the smooth winglet, dimpled winglet and riveted winglet. The parameters used for the simulations were based on the actual cruising flight and zero degree angle of attack. From the results, both show that the surface with rivets is better. The flow trajectories show that the flow velocity across riveted surface modified winglet is 5% higher than the smooth conventional winglet

Time for Tea : Factors of Service Quality, Memorable Tourism Experience and Loyalty in Sustainable Tea Tourism Destination

Underpinned by Script Theory and the S-O-R model, this research enhances the green tourism consumption literature to identify how destination service quality contributes to visitors’ memorable experiences and loyalty towards a place-based food tourism attraction. A total of 202 tourists who visited the Best of Highlands tea plantation in Malaysia were surveyed using an online questionnaire. Using PLS-SEM, this study has several notable findings: (i) destination service quality factors: activities, cleanliness, language, and security emerged as predictors of memorable tourism experiences; (ii) memorable tourism experiences strongly predicted destination loyalty; and (iii) memorable tourism experiences mediate the path between destination service quality and destination loyalty. This study therefore provides new insights into both sustainable tea tourism and script theory with respect to how memories guide future decision making. These results also provide insights for tea tourism providers in designing an unforgettable destination that stimulates the tourist’s intention to revisit the destination and to communicate it to others
