Aerodynamic Drag Reduction in a Passenger Vehicle Using Vortex Generator with Varying Yaw Angles: Detailed Study | Chapter 8 | Emerging Trends in Engineering Research and Technology Vol. 1

 Large money are aimed at minimizing capacity needed for force i.e., new downsized engines accompanying new aerodynamic devices for drag decline. For passenger cabs the aerodynamic drag force is the dominating opposition force at higher velocity. The car body is frequently optimized for reducing the drag fighting. Vortex generators belong to the type of boundary tier manipulators. Their function is to revitalize an adverse pressure gradient edge layer that is to say about to separate by transporting high push fluid from the outer part of the confine layer just before the low momentum district closer to the wall. In this exploratory investigation, the alternative of pressure coefficient, dynamic pressure, cooperative of lift and drag with and without whirlpool generators (VG) on the house of a utility vehicle have happened studied at varying swerve angles of VG. The yaw angles secondhand are 10°, 15° and 20°. To measure the effect of altering the vehicle frame, wind tunnel tests have been acted with 1:15 scaled model of the serviceableness vehicle with velocities of 2.42, 3.7, 5.42 and 7.14m/s. The experiments granted that a great improvement of the sleek drag force reduction maybe achieved with whirlpool generator.

Studies on Energy Consumption in Pneumatic Conveying of Raw Cotton | Chapter 2 | Fundamental Research and Application of Physical Science Vol. 6

 The verdicts of experiments on energy devouring during the pneumatic transport of inexperienced cotton to gineries are bestowed in the article. Increased capacity consumption for addition in the composition of raw understand environmental understandable and objectively.  Based on the verdicts of theoretical and empirical research, it offers implications and opinions for directing the cotton airy transport process effectively and threatening energy expenditures.  Obtained from the capacity consumption reliance of flow characteristics, expressly average speed, line pressure, and pipe length and diameter. It considered using 355 mm width pipe and 315 mm diameter pipe a suggestion of correction 400 mm diameter pipe at a moderate rate of flow to lower the capacity consumption of the pneumatic establishment.
