| Abstract: | It is shown that, for a certain proportion between the rib height (2–15 mm) installed at the test-section entrance and the turbulence level of the main flow (1–26%), there are extrema of parameters that describe mass transfer on the surface of an evaporating liquid fuel. In tests with and without combustion, discrete changes in the rates of heat and mass transfer are observed. Conditions for their manifestation are analyzed.
