Flow Over An Isothermal Plate Is Shown In The Right Assuming Steady State Incompressible Laminar Flow Constant Fluid 1 (84.74 KiB) Viewed 56 times

Flow over an isothermal plate is shown in the right. Assuming steady state, incompressible, laminar flow, constant fluid properties, negligible viscous dissipation and dp/dx = 0, the boundary layer equations are reduced to: T, 8(x) L ди Ov ди du 22u + = 0 - (1), u +v =V ax ay ax ay ду? at ar 02T (2), and u + v Ξα ax ду ду? (3) After introducing the stream function, y, and defining new dependent and independent variables, f (n) and n, such that: f(n) , n = y/uc/ux.
