Paper discusses aerodynamics and potential engineering applications of an unusual and in literature practically unknown fluid flow configuration. with two wall-jets attached to a cylindrical surface so that they collide head-on and by mutual conjunction generate a single jet directed away from the wall. Applications are envisaged in pneumatic sensors. particularly those operating at l... https://www.roneverhart.com/Medline-Wheelchair-Arm-Trays-TRAY-ARM-WHEELCHAIR-ADJUSTABLE-LEFT-MDSR009636/
