ANALYTIC AND EXPERIMENTAL METHOD FOR
DETERMINATION OF CONVECTIVE HEAT
TRANSFER COEFFCIENT
This paper describes how analytic and experimental method for
determining the heat convection coefficient for a cylindrical wall placed
horizontally and warmed on the inside. Analytical method consists in calculating
the criteria of similarity (invariants) describing the phenomenon of thermal
convection, and by experimental method taking into account heat transfer by
free convection and radiation between the wall and the environment.
