In this paper, a detailed investigation of water (Pr ¼ 7:0) convection in a chemical condenser is carried out. Two openings are located along one side of the cavity. The Navier-Stokes equations are solved in the frame of a control volume method using the SIMPLEC algorithm to implement adequate coupling of pressure and velocity. Special emphasis is given to the influence of the Reynolds number, the tilt of the channel and the Rayleigh number on the convective heat transfer. Results are presented and discussed allowing the control parameters to span relatively wide intervals: Rayleigh number (104 ≤ Ra ≤ 5 × 105), channel inclination (0° ≤ φ ≤ 90°) and Reynolds number (10 ≤ Re ≤ 1000). On the basis of these results, a new correlation of the Nusselt number is elaborated.
