Résumé

Experiments were carried out in a specially designed cell to study the onset and propagation of dryout point on a chemically machined microgrooved silicon surface with pentane as the coolant liquid. The axial temperature distribution was accurately measured as a function of the heat input and inclination of the substrate. The comparison between the dry (without liquid) and wet (with liquid) temperature profiles was used to locate the dryout point. A numerical simulation of the evaporative heat flux was investigated. The nonlinear governing equations were solved numerically. The predictions were successfully compared with the experimental results.
