The log mean temperature difference (LMTD) is used to determine the temperature driving force for heat transfer in flow systems. The LMTD is a logarithmic average of the temperature difference between the hot and cold streams at each end of the exchanger. ...
You can use the above equations in the log mean temperature difference formula to obtain the value for the respective flow arrangement. Counter flow vs Parallel flow Assuming the same set of inlet and outlet temperatures, the LMTD value for counter flow would be greater than the parallel one. ...

where U is the overall heat transfer coefficient from fluid to fluid, A is the heat transfer surface area of the heat exchanger associated with U, and Δtm is the log mean temperature difference (LMTD or Δtm). For a heat exchanger with a constant U, the LMTD can be calculated as (...
aIn most simple systems this is the "log mean temperature difference" (LMTD). Sometimes direct knowledge of the LMTD is not available and the NTU method is used. 在多数简单系统这是“日志平均温差” (LMTD)。 有时LMTD的直接知识不是可利用的,并且使用NTU方法。[translate]...
