- •
Transient heat transfer was investigated by thermographic phosphor thermometry.
- •
Distance from the nozzle and impingement angle were varied for measurements.
- •
Transient heat transfer is almost two times greater than the steady-state value.
- •
Secondary peak of heat transfer appeared at high impinging angle case.
- •
Secondary peak is associated with unsteady vortex at the beginning of the wall jet.
