In thermal engineering, the logarithmic mean temperature difference (LMTD) is used to determine the temperature driving force for heat transfer in flow systems, most notably in heat exchangers. The LMTD is a logarithmic average of the temperature difference between the hot and cold feeds at each end of the double pipe exchanger.

对数平均温差（简称LMTD——Logarithmic mean temperature difference）。两种流体在热交换器中传热过程温差的积分的平均值。

2019年5月22日 · The “Logarithmic Mean Temperature Difference“ (LMTD) is a logarithmic average of the temperature difference between the hot and cold feeds at each end of the heat exchanger. The larger the LMTD, the more heat is transferred.

You can use the LMTD calculator to determine the logarithmic mean temperature difference (LMTD) for a heat transfer process. When you calculate heat transfer, you must have noticed the term for temperature difference in the equation along with …

2024年10月3日 · 对数平均温差（lmtd）是热工工程中的关键参数，特别是在换热器的设计和分析中。 它提供了热流体和冷流体在换热器长度上的平均温差，从而允许计算热传递率。

Logarithmic Mean Temperature Difference - LMTD The rise in secondary temperature is non-linear and can best be represented by a logarithmic calculation. A logarithmic mean temperature difference is termed

LMTD Calculation. Calculate Log Mean Temperature Difference (LMTD) for shell and tube exchanger for counter-current and co-current flow.

To solve certain heat exchanger problems, engineers often use a logarithmic mean temperature difference (LMTD), which is used to determine the temperature driving force for heat transfer in heat exchangers. LMTD is introduced because the temperature change that takes place across the heat exchanger from the entrance to the exit is not linear.
