Abstract
The transient responses of crossflow heat exchangers with one fluid mixed and the other fluid unmixed are analysed numerically in this paper. Two cases are investigated: one for the response to a unit step change in the inlet temperature of the stepped fluid being mixed, and the other for the stepped fluid being unmixed. It is found that the outlet transient responses of the unstepped fluid for the two cases investigated are the same, but the outlet transient responses of the stepped fluid are distinctly different. The effects of various governing parameters concerning the transient response are discussed in detail and shown in graphical form.
