This paper experimentally studied the effect of different channel and concentration on condensation heat transfer coefficient in herringbone plate heat exchanger
the relationship between flow and pressure drop was also done. The investigation was based on apparatus which was designed and set up
mixed vapor with Marangoni effect was chosen to carry out experiments. The results indicated that flow maldistribution was obvious increasingly with increasing flow. For low ethanol concentration(1%)
the coefficient could be augmented as much as 25% as compared with pure water vapor. Mixed vapor condensation of heat transfer coefficient was even below than pure water vapor with increasing concentration under a certain flow. Water pressure drop was far more than vapor side. Moreover
corresponding pressure drop decreased when the number of plate increased.
