We have established the continuity equations under train pipe leakage condition and presented an explicit finite difference method to solve the pressure-velocitycoupling equations.

LFMCW radar, with its LPI characteristic and greater advantage over monopulse radar in the ambiguity of range and velocitycoupling, has always been an important topic in the radar research field.
The discretized schemes of the convective fluxes, diffusive fluxes and unsteady term are all of second -order accuracy. The SIMPLE algorithm is adopted to deal with the pressure-velocitycoupling.
