- Title
AN ALTERNATIVE APPROACH FOR SELECTION OF HEAT TRANSFER AND PRESSURE DROP CORRELATION FOR COMPACT HEAT TRANSFER SURFACES.
- Authors
Diaconu, Bogdan
- Abstract
Selection of the heat transfer and pressure drop correlations is a complicated and multi-faceted issue in the design workflow of compact heat exchangers. There are several reasons behind this issue, the most important being the validity of the correlations over narrow Reynolds number intervals. In practice, heat transfer and pressure drop correlations are derived experimentally under laboratory conditions and for Reynolds interval considered most probable. Depending on the application, the flow regime can deviate significantly from the design conditions, resulting in operation conditions that may be far from the expected ones. The algorithm proposed in this paper allows a flexible choice of the heat transfer and pressure drop correlation that results in a trade-off between thermodynamic effectiveness and operation under controlled conditions.
