Numerical and experimental investigations were performed on a venturi discharging into a cross flow. The numerical analysis consists of a non-uniform meshed model, solved using CD-Adapco Star CCM+ commercial software with K-&egr; and K-ω turbulence models. The analysis consisted of two different configurations; the venturi is flush with the tunnel's bottom wall and with a 15.24 cm extension tube of the same diameter installed between the venturi and bottom wall. The experimental investigations were carried in an open-circuit wind tunnel with a single hot wire sensor at the Center for Energy and Environmental Research and Services (CEERS) facility without the extension tube in place. Momentum Ratios, r, were set at 50%, 75% and 100% for the numerical analysis and 50%, 85% and 100% for the experimental investigations. Results indicate that no flow separation of recirculation occurred in the venturi or extension tube.
