EXPERIMENTAL INVESTIGATION OF STROUHAL'S NUMBER LINEARITY FOR DUAL TRAPEZOIDAL BLUFF BODY VORTEX FLOW METER

In this paper, in an experimental facility, the signal characteristics of DN50 trapezoidal dual bluff body vortex flowmeter are investigated with a steady flow. The results are presented for the nine dual trapezoidal bluff body combinations with opening length varying from 40.5mm to 115.5mm with blockage ratio of 0.26, 0.29 and 0.31. For each blockage ratio, the influence of three after shape angle (16°, 19°, and 22°) are investigated. The vortex frequency is calculated by using a zero-crossing method. The Linearity of Strouhal’s number is used as a parameter for comparison. The results show that the vortex frequency increases for the 0.26 and 0.29 blockage ratio by using the dual bluff body. For the 0.31 blockage ratio, the vortex frequencies are almost the same or less for all after shape angles and opening lengths than the reference single bluff body. The best linearity of Strouhal’s number was observed for 22° after shape angle combinations for all blockage ratios. https://journalnx.com/journal-article/2015042

On Quadruple Random Fixed Point Theorems in Partially Ordered Metric Spaces

Bhaskar and Lakshmikantham in [15] introduced the concept of coupled fixed point of a mapping and investigated the existence and uniquencess of a coupled fixed point theorem in partially ordered complete metric space. Lakshmikantham and Ciric [16] defined  mixed g-monotone property and coincidence point in partially ordered metric space. V. Berinde and M. Borcut[18] introduced the concept of triple fixed point and proved some related theorems. Following this trand,  Karapinar[19] introduced the nation of quadruple fixed point. The object of this note is to prove quadruple random fixed point theorem in partially ordered metric spaces
