초록정보

Two-dimensional tulbulent plane jet which is under the lateral pressure gradient is studied numerically. Full Navier-Stokes equations are used to correctly account for the pressure variation in the transverse direction. The pressure gradient is imposed by giving the different pressure levels along upper and lower boundaries. Using the standard K-$\varepsilon$ turbulence model as a closure relationship, a time marching procedure gives thevelocity fields. The temperature fields are also obtained for two different case:1) Hot jet is issued into the cold still air.2) Top and bottom boundaries are maintained at the different temperature levels. All the calculations are performed for a fixed Reynolds number ($Re=7\times10^4$ The velocity and temperature fields along with other flow and heat transfer characteristics for two different pressure gradients are presented. A simple formula for relating the jet trajectoryto the pressure gradient is also proposed. The mass flux in the longitudinal direction seems quite insensitive to the lat-eral pressure gradient. However, the lateral pressure gradient increases the heat flux in the longitudinal direction as well as in the transverse direction.
