The characteristics of flow and heat transfer of shell-and-tube heat exchangers with overlapped helical baffles (STHXsHB) were illustrated through a theoretical analysis and numerical simulation. The ideal helical flow model was constructed to demonstrate parts of the flow characteristics of the STHXsHB, providing theoretical evidence of short-circuit and back flows in a triangular zone. The numerical simulation was adopted to describe the characteristics of helical, leakage, and bypass streams. In a fully developed section, the distribution of velocity and wall heat transfer coefficient has a similar trend, which presents the effect of leakage and bypass streams. The short-circuit flow accelerates the axial velocity of the flow through the triangular zone. Moreover, the back flow enhances the local heat transfer and causes the ascent of flow resistance. This study shows the detailed features of helical flow in STHXsHB, which can inspire a reasonable optimization on the shell-side structure.

辽东带系指渤海辽中凹陷的东部陡坡带及辽东凸起,被辽中及辽东凹陷所夹持。辽东带油源条件好,东营组储—盖条件优越,断鼻、断块圈闭发育。但在2002年之前的15年内,国内外公司在辽东带进行了长期研究和勘探,钻了12口探井,没有发现商业油气田。经过对辽东带油气地质条件3年的深入研究,对每口失利井原因进行了再次分析,认识到该带发育东营组及沙河街组两套主力成藏组合,控制东营组成藏的主要因素是油气运移,而沙河街组能否成藏关键是储层。在此认识指导下选择研究方向,评价有利目标,经钻探发现了金县1-1大油田,储量达1.5×108 m3,充分显示了科研在油气勘探中的作用。
