“…In a conventional thermal vacuum chamber, the liquid nitrogen in the shroud is usually used as coolant to provide a cold background less than 100K. And the external heat flow received by spacecraft on orbit is simulated by adding the infrared heaters or electric heating films [5,6]. However, most of the heat generated by the heaters is absorbed by liquid nitrogen through the radiation of the device under test (DUT).…”

Extensive numerical study on the heat transfer performance of the gaseous nitrogen (GN) thermoregulation shroud surface was conducted in this work. The average heat transfer coefficient was investigated under different shroud length and nitrogen parameters (such as velocity, temperature and mass flow rate). The result shows that the heat transfer performance is affected less by shroud length but largely by mass flow rate. When the mass flow rate is constant, the inlet temperature increases heat transfer coefficient. Finally, dimensionless correlation of the average Nusselt number over shroud surface with Reynolds number and Prandtl number was obtained.
