Timoshchenko A. Hydrodynamics and heat exchange of fluid flow in slit microducts.

Hydrodynamics and heat exchange of fluid flow in flat slit and concentric annular microducts at the laminar flow regime is studied in dissertation work. Isothermal fluid flow is considered the methods of mathematical and full-scale modeling in microducts with hydraulically smooth and rough surfaces. Full-scale investigation of superheated water flow in hydraulically smooth microducts is carried out. By experimental methods unidirectional and two-sided heat exchange is investigated at the forced laminar flow regime. The results of researches are gener-alized by criterion equalizations. On the basis of the conducted researches calculation methods are developed and the standards of a new high-performance heating engineering equipment are created.
