Bir telekomünikasyon uydusunun evaporatör soğutma döngüsünde iki fazlı akışın çalışması ve analizi

Satellites are constituted of electronic components that release heat flux. The heat released must be evacuated otherwise there are some risks to damage components in the satellite. In order to guarantee the correct working of the satellite, a thermal loop crossed by a refrigerant fluid must be added. The loop is constituted by a heater, a pressure regulator, a condenser, and a pump. The evaporator is the element of the loop in which the heat released by the electronic components is transferred to the fluid. The fluid, receiver of the components entailed energy will then be heated and will evaporate itself little by little. This breeds the appearance of a two-phase flow. An approach, developed will take into account the different models of two-phase flow that we can consider in our case. We will then be able to follow the evolution of the physical variables which characterize the system like the component temperature, the drop loss, void fraction and the quality. So, this study will provide a visualization of the thermo-hydraulics phenomenon in the evaporator, in the domain of specifications.
