Thermal Environment around Strong Heat Source with Single-Sided Natural Ventilation

摘要

A test model has been built in order to analyze how a strong heat source (SHS) influences its surrounding thermal environment with single-sided natural ventilation. Through a study about how the air temperature distributes around the heat source, particularly when the heat source was located in three locations-in the center of the test model room, near the inlet and comparatively far away from the inlet, a conclusion can be drawn that three factors, heat release rate of the SHS, air distribution with single-sided natural ventilation and the location of the heat source, have a great impact on the surrounding thermal environment. Furthermore, if the heat release rate of the heat source is fixed, the other two above-mentioned factors would take in charge instead. Furthermore, the air-temperature in the leeward side appears a little higher than that in the windward side. Combined the experiment and some fieldwork results, it is easy to draw the conclusion that when the heat source is located comparatively far away from the inlet, the temperature around the heat source would rise approximately linearly with height. The result is consistent with the CFD simulation.
