Effect of Solar Radiation on Thermal and Hydrodynamic Conditions in Laminar, Open Channel Flow

摘要: A three-dimensional laminar flow model has been used with a one-dimensional radiation transfer to predict the response of slowly moving liquid layer solar irradiation. Calculations performed for range velocities, and substrate radiative properties, irradiation reveal important influence buoyancy forces on hydrodynamic thermal conditions. Buoyancy induce secondary which takes form longitudinal vortices and/or ascending-descending thermals. Onset may be advanced strength enhanced by increasing albedo or decreasing extinction coefficient, reflectivity, velocity.
