Web18 de ago. de 2024 · The heat transfer rate is proportional to the available heat transfer area. Increasing the surface area of the heat exchanger core leads to an increase in the heat transfer coefficient. You can achieve this result in two ways — either by increasing the overall size of the heat exchanger (which is not always an option) or by adjusting the … Web1 de abr. de 2024 · The convective heat transfer coefficient of the shell and tube heat exchanger is calculated based on the following correlation: (4) U = Q A × L M T D where, A is total heat transfer area, m 2, Q is heat transfer from hot stream into cold stream, W, LMTD is logarithmic mean temperature difference, K. (5) Q = V (ρ C p) n f (T h 1 − T h 2) …
