Modelling of local heat transfer in a jacketed slender agitated vessel

Theoretical model is proposed to calculate the local heat transfer coeffici ent alpha which depends on the friction coefficient f on the wall. The mode l was verified basing on the experimentally determined distributions of the coefficient alpha at the vertical wall of a slender jacketed vessel. The d istributions of the friction coefficient were measured using the electroche mical method. Theoretical and thermal measurement results for mechanically agitated liquid and gas-liquid system are consistent.
