Flow Maldistribution in Industrial Air Heaters and its Effect on Heat Transfer [PDF]

Chemical Engineering Transactions, 2014
Flow maldistribution in cross-flow heat exchangers used for industrial air heaters or recuperators is fairly common and can lead to a number of undesirable effects, one of which is deterioration in the thermal performance.
