BOILING OF VARIOUS LIQUIDS IN A MICROCHANNEL

A study of heat emission during the boiling of distilled water and isopropyl alcohol in a microchannel with a size of 12.5 × 3× 0.2 mm³ has been carried out. To calculate heat emission during boiling in the microchannel, the Kutateladze equation for a fl at slot with one-sided heating was used, as well as the Kutepov–Sterman dependences for nucleate boiling under conditions of directional fl uid motion and the Danilova dependence for calculating heat emission during boiling. It is established that the Kutepov–Sterman equation yields the minimum deviation from experimental data (no more than 25%).
