heat exchange of swirling flow, tangential swirler, local and average heat transfer coefficients.Abstract
Heat exchange of swirling flow in a cylindrical canal with one and two tangential swirlers has been developed (in conformity with the system of internal cooling of cyclone type of gas turbine blade). The inchannel local and average heat transfer coefficients were obtained; thermal hydraulic characteristic of investigated schemes was analyzed.References
