A source transfer method

which is used to couple the flow network calculation of blade internal flow and source simulation of blade external cooling

was embedded into a 3D aero code

which is usually used to calculate blade external flow

then a quick simulation of a whole cooled blade was carried out. A computer program called CTUCP was developed based on this method. CTUCP was first used to calculate the steady cooling of the turbine vane cascade C3X

and the result was compared with the result of CFX

proving that CTUCP can calculate stably

faster by one order of magnitude

and give close prediction of the blade wall temperature distribution trend except at the leading edge. Next

CTUCP is used to calculate pulsed cooling of C3X

obtaining the characteristic of the coolant and wall temperature under two different pulse amplitudes.
