abstract

Flow, heat and mass transfer in a paint curing oven are studied numerically with a view to improving the energy efficiency of the oven and to control pollution. Painted products traverse the paint curing oven at a constant rate and in a fixed trajectory, and are heated by hot air jets which control the part temperature to ensure paint curing. Steady simulations are performed to compute the air flow and temperature fields. Computed air temperatures match experimentally measured values to an accuracy of 19% (temperatures calculated relative to the room temperature). Assuming thermal equilibrium between the painted part and the local gas flow, positiondependent smoke release rates due to paint curing are computed from the part temperature using experimentally measured cure rates. Smoke is modeled as a gas-phase species in a dilute mixture with air and its concentration and distribution in the oven are computed. The thermal behavior of the oven is captured in a parameter called the thermal performance index. The exhaust air mass flux is shown to have large impact on this index. Smoke loss to the outside environment is computed to quantify the degree of pollution. The impact of air seals on the thermal performance index and smoke release to the environment are quantified. Finally the effect of the thermal mass of the parts is considered and the convective and radiative effects are studied.
