In the present study, heat transfer characteristics of dual jet flows are investigated using off-lattice Boltzmann method based in-house solver. Four different Reynolds numbers and four different jet separation width to channel-width ratio, S/H, are evaluated for their effect on the flow and heat transfer characteristics. For all the cases, the Nusselt number on the walls and the effect of flow instabilities are analyzed. It has been observed that for any given Reynolds number in the laminar regime, the total heat transfer rate is not much influenced by the placement of the jets, though a slight increase can be observed when the two jets are closer to the side walls. The jet spacing mostly influences the lengthwise extent up to which heat transfer can occur and the location of the peak Nusselt number. At Reynolds number Re = 60, a significant jump in the Nusselt number is observed between \(S/H=0.25\) and \(S/H=0.5\) , which can be attributed to the flow instability induced at higher S/H ratios.
