Nature of wall heat transfer coefficient

A mechanism of heat transfer from a tube wall to fluid flowing in a packed bed is proposed whereby : (1) a mass of fluid is thrown against the wall ; (2) the fluid at the wall assumes the wall temperature and transfer occurs inward ; (3) this mass of fluid moves away from the wall and is replaced by

Recently, Wijngaarden and Westerterp (1989) derived a dimensionless criterion as to whether or not a homogeneous model can be used instead of a heterogeneous one in modelling wall-cooled tubular reactors. Their work is an extension of the well-known criteria of e.g. Mears (1971) for the neglect of i
