Consider a liquid metal (Pr << 1) with free stream conditions u∞ and T∞, in parallel flow over an isothermal flat plate at Ts- Assuming that u = U throughout the thermal boundary layer, write the corresponding form of the boundary layer energy equation. Applying appropriate initial (x = 0) and boundary conditions, solve this equation for the boundary layer temperature field, T(x, y). Use the result to obtain an expression for the local Nusselt number Nux.
