Simulation of Thermal Characteristics of Turbulent Dual Jets

Farooq SK and Das MK

The thermal characteristic study of a dual jets comprising of combined wall jet and offset jet, with different bottom wall boundary conditions (i.e.; adiabatic, constant wall heat flux) is formulated. The flow is two-dimensional, steady, incompressible, and turbulent at high Reynolds number with negligible body forces. Initially the code developed for single off set jet with bottom wall adiabatic and constant heat flux boundary condition of different offset ratios. The simulated results are validated with the benchmark results, and the simulated results are found in good agreement with the experimental results. Dual jets case is also studied with adiabatic bottom wall, temperature distribution in the heated jets and the temperature decay in the normal direction due the entrainment characteristics are observed. For constant heat flux case, variation of local Nusselt number with the separation ratio is observed.
