Numerical simulation of solid-liquid flow of Yangtze River water in a semi-annulus reentry tube;

The investigation shows that used as cold and heat sources,the Yangtze River water is suited for developing water source heat pump technology and the shell-and-tube direct water source heat pump system is a feasible form.

The variation of fouling resistance and frictional resistance coefficient of heat exchanger using connate Yangtze River water as cooling water is tested experimentally.

Therefore,the use of Yangtse River water as the heat and cold sources of water source heat pumps will have great potential of energy efficiency.
