文摘
- •
Circular water jet impinging on a heated surface was studied.
- •
Simultaneous velocity and temperature fields were measured by means of PIV and PLIF.
- •
The algorithms to reduce the measurement error of PLIF method are proposed.
- •
Turbulent heat flux was measured in a wall jet region.
- •
Up to 25% of heat transfer intensity is provided by a mechanism of turbulence.
