id="p0010">Numerical modeling of the turbulent flow structure and heat transfer in a gas-droplet pulsed impinging jet is carried out.
- •
id="p0015">The dispersed phase is modeled by the Eulerian approach.
- •
id="p0020">The effects of pulse frequencies, ratio of on time to total cycle time on heat transfer are numerically studied.
- •
id="p0025">It is shown both the increase and the reduction of heat transfer are characteristic of pulsed gas-droplet jet impingement.
