Abstract

Abstract The influences of corrugation pitches on the flow and heat transfer characteristics of corrugated plates are numerically investigated and assisted by field synergy theoretical analysis. The results indicate that the groove structure formulated between corrugated plates can effectively improve the field synergy angles and enhance heat transfer. The smaller the pitch of the corrugated plate is, the more intensely the fluid temperature changes, and the pressure drop increases. In the range of 14.14 mm–28.28 mm, a smaller pitch is more conducive to heat transfer, yet negative to the flow resistance. In addition, the present article examines the flow and heat transfer characteristics in the corrugated plate and finds out that the secondary flow in the corrugated plate is the main factor affecting the temperature nonuniformity E and Nu
