Název v původním jazyce
A Semi-analytical Approach for Determination of the Wall Heat Transfer Coefficient of a Cylindrical Concentric Annulus
Popis výsledku v původním jazyce
One of the long-term research goals of Doosan Škoda Power s.r.o. is to develop an effective and fast method for determining the wall heat transfer coefficient on important parts of steam turbines during various operations. One of the geometrically simplest investigated parts of a steam turbine is the cylindrical annulus. In this paper, a semi-analytical solution of the Graetz problem in a concentric cylindrical annulus is presented, assuming a fully developed velocity profile of turbulent fluid flow regime. This semi-analytical solution is compared with the solution of the commercial computing system Ansys CFX when solving the same problem.
