Derivation of rayleighs stability equation
WebFrom the notation of Equation (2), one may conclude that its element (7) e − q z − 2 q s (s 2 + κ 2) − 1 e − s z. is a measure of the horizontal displacement u x attenuation rate with the depth of z. If one substitutes for the above equation the calculated values of q and s, one can get the following numerical factor: (8) e − 0.8847 ... WebHydrodynamic stability is a series of differential equations and their solutions. A bifurcation occurs when a small change in the parameters of the system causes a qualitative change in its behavior,. [1] The parameter that is being changed in the case of hydrodynamic stability is the Reynolds number.
