Carry out the flow field numerical simulation of the intake in different flight conditions (Tab.1). The geometry is shown as Fig.1 in detail and the design condition is H=25km, Ma=6.

Requirements:

Submit an analysis report, which includes: (1) the calculation results and analysis of the flow field under different flight conditions; (2) the analysis of the influence of different flight conditions on the total pressure recovery coefficient of the intake.
