double shear layer definition
 

hey

can anybody tell me what is double shear layer ? i mean if i want to make other people understand wht it is ?? so in simple words....

secondly is there a need to input Re if we r trying to solve double shear layer of Bell (paper)...

they used rho = 1/30 and thickness of layer as 0.05,, the fluid is invisicd ..
do we need to put high reynolds number as well to solve this problem ??
