Class LNGHeatExchanger.FinGeometry

java.lang.Object
neqsim.process.equipment.heatexchanger.LNGHeatExchanger.FinGeometry
All Implemented Interfaces:
Serializable
Enclosing class:
LNGHeatExchanger
public static class LNGHeatExchanger.FinGeometry extends Object implements Serializable
Plate-fin geometry for offset-strip, wavy, plain, or perforated fins.

Used by the Manglik-Bergles correlations (P5) to compute heat-transfer (j) and friction (f) factors and by core sizing (P8) to determine exchanger dimensions.
