Abstract：
Computational fluid dynamics (CFD) is efficient to simulate environmental control performance of the manned space craft cabin and verify the model experimental results on the ground. Presents the domestic and overseas development in research on numerical simulation of the convection heat transfer in manned space craft cabin. The research relates to numerical simulation in different ventilation modes, optimization design of ventilation parameters, analyses about impacts of human body heat dispersion on environment, temperature distribution and dew control on cabin walls, the model experiments on the ground and their validations by numerical simulation, and heat and mass transfer. Points out some problems needed further study, including the model of numerical simulation, assessment on ventilation and air conditioning in cabin, the holistic optimization of ventilating, air conditioning systems, and the numeral emulation and demonstrating system of environment in cabin.
