A model for the rewetting of a solid cylinder is solved by the Wiener-Hopf technique. A constant heat transfer coefficient is assumed in the wetted part of the cylindrical rod, whereas an exponentially decaying heat flux is assumed in that part of the solid which is cooled by a mixture of vapor and liquid droplets (the precursory cooling). Accurate predictions of the rewetting velocity are obtained for a wide range of model parameters. The results of the present solution are found to compare favorably with a separation of variables solution obtained by Olek (1987). Values of the rewetting velocity where precursory cooling is neglected are recovered as a particular case. The decomposition in the form of infinite products presented here is shown to yield results which agree well with those derived from a decomposition by Evans (1984), employing the Cauchy theorem.
