Solution of the laminar boundary layer of a semi-infinite flat plate given an impulsive change in velocity and temperature
The laminar boundary layer over a semi-infinite flat plate which is impulsively set in motion in an incompressible fluid and which has a simultaneous step change in surface temperature was studied. An approximate method was derived which can be used to determine the thermal boundary layer thickness …
