JACKETED VESSELS - A-to-Z Guide to Thermodynamics, Heat .

The prediction of the transient time required to heat and/or cool the contents of a jacketed vessel is dependent upon many variables: jacket configuration—plain jacket or dimpled jacket (with or without directional vanes) or a limpet coil; heat transfer medium in the jacket—isothermal, nonisothermal or pump-around fluid and an external heat exchanger; type of vessel, its geometrical .
