... unit requires ε − NTU relation which is unavailable for three-fluid cross-flow heat exchanger due to various complexities involved. A new approximate methodology for the optimization is presented by proving the equivalence of 3 − FHX with a coupled two-fluid heat exchanger ( 2 − FHX ) followed by using...

... tube forced convection cross-flow When fluid flows across a circular tube, a large separation zone exists at the rear of tube, created by boundary layer separation, resulting in a large pressure drop loss, serious vibration, and in some situations damage to the tubes. So, non-circular tubes...
