In this article, transient conjugate heat transfer during the flashing of liquids in pipes is examined. A numerical model is formulated to simulate a blowdown of a pipeline produced by a partial rupture of a pipe. The model is based on the approach to the description of conjugate two‐phase heat transfer proposed in an earlier study by the author. The effect of the area of the rupture on the wall‐to‐fluid heat transfer is studied. The range of applicability of the novel formulation of energy equation is determined. The use of a new fundamental dimensionless number governing the effect of conjugate heat transfer on flow behavior is shown. This parameter can be very useful for solving the problem of transient flashing liquid flow in pipes.
