Numerical Simulation of Flow and Heat Transfer Process in Manned Spacecraft Cabin

In pressured cabin of manned spacecraft,human body and equipment heat dissipation is realized by convection heat transfer.Computational fluid dynamics is efficient to simulate ventilation in cabin.On the platform of I-DEAS,a steady state simulation on complex ventilation for a certain manned spacecraft on orbit is performed.The results gire the system energy distribution and the optimized thermal control design.
