Furthermore, during the project setup process afluid is chosen as belonging to on e of th e following six categories: gas; liquid; non-Newtonian liquid,compressible liquid, rea] g as or steam . P h ysical features that can b e taken in to accoun t include heatconduction in solids, radiation, time-varying flows, gravity and r ota tio n , Rough n es s of surfaces can bespecified and different thermal conditions fo r wallscan be chosen including adiabaticwalls or specifiedheat flux, heat transfer rate or w all tem perature, For a mote c omp le te list o f p o ss ib le s et tin g s, see table1.1.
