中文摘要:采用CFD软件STAR-CD和FEA软件ABAQUS对226B型柴油机缸盖冷却水腔内的流动和传热过程进行了流固耦合数值模拟计算。为反映沸腾传热的影响,基于FORTRAN语言开发了单相流沸腾传热模型,将其嵌入到STAR-CD中。与试验结果的比较表明,加入沸腾传热模型可以大幅度提高模拟计算的精度,最大误差由18%下降至7%,为柴油机冷却水腔的优化设计提供了理论依据。

Abstract: Fluid-solid coupling numerical simulation on the flow and heat transfer of cooling water-jacket in cylinder head for 226B diesel engine was performed using the commercial CFD software STAR CD and the FEA software ABAQUS. In order to consider the influence of boiling heat transfer, a boiling heat transfer model was developed based on FORTRAN and built into STAR-CD. Comparison between simulation and experiment showed that the two results are in good agreement with each other. Comparing with the results of simulation without the boiling heat transfer model, maximum deviation drops from 18% to 7%. So the simulation provides a more dependable theoretical evidence for diesel water-jacket optimization.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
