Three-dimensional simulation of laminar rectangular impinging jets, flow structure, and heat transfer
- Eastern Mediterranean Univ., Magosa (Turkey). Mechanical Engineering Dept.
The flow and heat transfer characteristics of impinging laminar jets issuing from rectangular slots of different aspect ratios have been investigated numerically through the solution of three-dimensional Navier-Stokes and energy equations in steady state. The three-dimensional simulation reveals the existence of pronounced streamwise velocity off-center peaks near the impingement plate. Furthermore, the effect of these off-center velocity peaks on the Nusselt number distribution is also investigated. Interesting three-dimensional flow structures are detected which cannot be predicted by two-dimensional simulations. Impinging jets are commonly used in many industrial applications to enhance heat or mass transfer from the impingement surface. Typical applications include tempering of glass, annealing of materials, cooling of turbine blades and drying of paper.
