Which law is implemented for flow visualization by optical system?
Snell's law is implemented for flow visualization by an optical system. According to Snell's law, a light ray, passing through a nonhomogeneous refracted field, is deflected from its original direction and a light path is different from that of an undisturbed ray. If a recording plane is placed in front of the light ray, after disturbing media, three quantities can be measured: the vertical displacement of the disturbed ray, the angular deflection of the disturbed ray with respect to the undisturbed one and the phase shift between both rays, owning to their different optical path lengths.
How to Calculate Prandtl Meyer function at upstream Mach number?
Prandtl Meyer function at upstream Mach number calculator uses prandtl_meyer_function_at_upstream_mach = sqrt((Specific heat ratio+1)/(Specific heat ratio-1))*atan(sqrt(((Specific heat ratio-1)*((Mach Number ahead of shock^2)-1))/(Specific heat ratio+1)))-atan(sqrt(((Mach Number ahead of shock^2)-1))) to calculate the Prandtl Meyer Function at upstream Mach no., The Prandtl Meyer function at upstream Mach number formula is obtained by substituting the upstream Mach number in Prandtl Meyer function. Prandtl Meyer Function at upstream Mach no. and is denoted by ν(M_{1}) symbol.
How to calculate Prandtl Meyer function at upstream Mach number using this online calculator? To use this online calculator for Prandtl Meyer function at upstream Mach number, enter Specific heat ratio (κ) and Mach Number ahead of shock (M_{1}) and hit the calculate button. Here is how the Prandtl Meyer function at upstream Mach number calculation can be explained with given input values -> 0.208722 = sqrt((1.392758+1)/(1.392758-1))*atan(sqrt(((1.392758-1)*((1.5^2)-1))/(1.392758+1)))-atan(sqrt(((1.5^2)-1))).
