Taking buildings’ cooling problem as the background, the natural convection were numerically simulated in a cavity with single heat source using SIMPLE algorithm with a QUICK scheme. The temperature field, flow field and rules of heat transfer were studied. The results showed that two symmetrical vortex appeared in a single heat source with the different ratio of length and height. With the increase...
In order to solve the problem of inadequate water pressure in the southern and southeast area of City K, high level water tank is to be built in different locations of network system to improve this situation. When it is low peak period at night, the excess produced water will be transferred into the high level water tank. Otherwise, during the peak period of the daytime, network will be supplied...
