abstract = {<p style="text-align: justify;">Jet impingement induced heat transfer is an important issue in engineering
science. This paper presents results of large eddy simulation (LES) of normally impinging
elliptic air-jet heat transfer at a Reynolds number of 4400, with orifice-to-plate
distance fixed to be 5 in the unit of jet nozzle effective diameter $D (=√ab)$. The elliptic
aspect ratio ($a/b$) is 3/2. While the target wall is heated under some condition of
constant heat flux. The LES are carried out using dynamic subgrid model and Open-FOAM.
The distributions of mean velocity components, velocity fluctuations, and subgrid
stresses in vertical and radial directions, and the Nusselt numbers involving heat
transfer through the target wall are discussed. The comparison with existing experimental
and numerical results shows good agreement.</p>},
