Abstract

Abstract

Oil cooler is a device widely used in nuclear power plants.Porous metal materials are of concern because of the good performance to enhance the heat transfer.In order to study the feasibility of the enhanced heat transfer of porous metal materials to oil,68# turbine oil was chosen as the heat transfer working medium,and kinds of porous metal materials with different porosities were chosen as the experimental objects.By changing the number of porous metal materials,the heat transfer and frictional resistance characteristics of oil inside tube were studied experimentally.The results show that the porous metal materials can enhance the heat transfer of oil inside tube within the experimental range.The Nusselt number of the oil side is in direct proportion to the number of porous metal materials.Moreover,the structure of porous metal materials is the most important factor of the enhanced heat transfer.
