A cross-flow heat exchanger is used in a cooling and ventilation system that requires heat to be transferred from one airstream to another.The thermal energy is exchanged via the panels. A traditional cross-flow heat exchanger has a square cross-section. It has
e, which is set equal to four times the Hydraulic Radius, R. h. is defined as follows. Cross-Sectional Area 4 4. e h. Wetted Perimeter. D R = = ×. In this definition, the term wetted perimeter is used to designate the perimeter of the cross-section that is in contact with the flowing fluid. This applies to a liquid that occupies part of a
Review of Literature on Heat Transfer Enhancement in increased without changing physical size of the exchanger. This paper provides some methods for increasing shell and tube and compact exchangers performance. direction of the shell side fluid to achieve cross flow. a heat transfer by a fouling factor R f, which is a measure of the thermal resistance introduced by fouling.

An experimental study of forced convective heat transfer Jun 01, 2017 · With cross-flow support the heat transfer was about 10% larger than with downstream support, due to flow disturbances produced by the cross-flow support. Pei also investigated the influence of the position of the support. He showed that the size of the support has only a minor influence.
