Abstract:
The flow and heat transfer simulation is carried out for the radar array with 1D-3D co-simulation method to investigate the flow distribution of a radar liquid cooling network system. The one-dimensional radar array model is built by one-dimensional simulation software Flowmaster. The flow rate-pressure difference results are obtained by detailed flow characteristics simulation of water joint and cold plates with three-dimensional software FloEFD. The results are brought into Flowmaster to obtain the fitting curves. The 1D-3D co-simulation is conducted by defining the different component’s parameters of the radar network system. The results show that the flow difference of each branch of the optimized array is less than 1.5% and the temperature distribution of the network is even. The effect of pulling out components on flow distribution is also studied. It is found that the flow difference of each branch of the network is less than 2% after the network components are pulled out. Through 1D-3D co-simulation, accurate flow distribution can be achieved, the detailed simulation results of the network can be intuitively obtained and the computing time and research costs are greatly saved. This co-simulation method provides reference for radar network flow distribution design in the future.
