System thermal managementThe first run without thermal management was conducted with the nitrogen flow pipe not submerged in water, but exposed to ambient air at room temperature. Results of fluid temperature at inlet and exit are shown in red in Fig. 5. Since heat is being added to the fluid from its surroundings, an increase of 5 °C in the temperature of the fluid is observed between pipe inlet and outlet. The minimum recorded exit temperature at exit points is -17 °C for the fluid and -4 °C for the pipe’s surface at inlet and outlet, respectively.Figure 5Temperature profile of nitrogen with (black) and witout (red) thermal management in the form of a water bath.In the second run, 60 percent of the pipe is submerged under water in four loops. The increase of fluid temperature from inlet to exit is measured to be 17.7 °C, where the fluid’s inlet, exit temperatures and…
