ud map in the spacesuit were obtained. The simulation results showed that the
flow field in the spacesuit was smooth and the ventilation flow ratio of the upper and lower limbs was
3 ∶2. The streamlines around the face were stable and distributed evenly which could effectively pre⁃
vent the face window from fogging. It was found that the temperature increased gradually from the
head to the limbs and the temperature decreased with the increase of distance to the body. The tem⁃
perature was lower in the areas where the streamlines were smooth.
