Аннотация

Influence of a jet impinging on a rotating disk on cooling process of the disk was experimentally measured. Laminar and turbulent local heat transfer coefficients were obtained for wide range of rotational and jet Reynolds numbers. Correlation formulae for both flow conditions are proposed and respective differences in heat transfer mechanisms discussed. It is shown that jet promotion of turbulence causes laminar heat transfer coefficients to increase strongly while it provokes no such strong influence on turbulent heat transfer. Finally, correlation formula for laminar heat transfer is compared with existing experimental data and satisfactory agreemant shown.
