In order to get higher energy transfer rate and optimum comprehensive performance of the heat transfer system,the best matching geometrical parameters of unusual spirally corrugated tubes are sought by optimum design.From the viewpoint of energy comprehensive applications the structure size optimization of unusual spirally corrugated tubes has been studied though the use of multi objective mathematical programming.The best geometrical parameters are obtained by combining every step seeking optimum restraining conditions by means of computer.Optimized calculation shows that the comprehensive performance of the unusual spirally corrugated tubes is better than that of the smooth tube.The results can provide theory basis for the design of unusual spirally corrugated tubes.
