Log Mean Temperature Difference Theory

The Log Mean Temperature Difference (LMTD) theory helps engineers calculate how effectively heat is transferred between two fluids at different temperatures in a heat exchanger. Instead of using the simple temperature difference at just one point, LMTD accounts for the changing temperature difference along the length of the device, providing an average value. This "logarithmic" average more accurately reflects the overall heat transfer performance, allowing for better design and optimization of heat exchangers to ensure efficient energy exchange between the fluids.
