An experimental and theoretical investigation of the effect of flow maldistribution on the thermal performance of plate heat exchangers
(2005) In Journal of Heat Transfer 127(3). p.332-343- Abstract
- An experimental and theoretical study of the effect of flow maldistribution from port to channel on the thermal performance of single and multipass plate heat exchangers is presented. In general, flow maldistribution brings about an increase in pressure drop and decrease of the thermal performance in heat exchangers. This deterioration is found to depend on flow rate, number of channels, and port size. Experiments show that analytical predictions of pressure drop and thermal performance in presence of flow maldistribution are quite accurate for practical purposes. The results indicate that under identical conditions, maldistribution is more severe in Z-type plate heat exchanger compared to U type. Multipassing is found to reduce the... (More)

An insight to the physical aspects of maldistribution and its possible reduction through proper design strategy are also presented. (Less)
