Abstract:

The temperature fields, velocity fields and pressure fields in the passage of double corrugated (DU)-1 plate at different Re were simulated through the simulation. The simulation round spoiler holes was proposed to enhance heat transfer of DU-1 plate. The mathematical model of single blow technology (STB) was developed according to the difference of heat transfer area of positioning plate and corrugated plate with air in the passage. Considering diameter, spacing, position and arrangement of the round holes, orthogonal experiments which could considerably increase experiment efficiency were conducted to determine the experimental plate models. The overall mean heat transfer coefficients and friction factors were measured through single blow technology experiments.  The influence of four factors to heat transfer and resistance characteristics of DU-1 with round holes was discussed through the analysis of experimental results. The best combination of the four factors which could enhance heat transfer and reduce flow resistance to the best of DU-1 was raised through consolidated balance analysis. The DU-1 plate has 19.87% increase in heat transfer and 24.53% reduction in flow resistance compared with DU-1 without round holes．
