Mathematical simulation of liquid film flows with “dry” spots

Mathematical simulation of liquid film flows with “dry” spots Abstract Mathematical simulation of isothermal film flow for a viscous ponderous capillary liquid with dry spots on a solid substrate was performed. The algorithm was developed for calculation of the shape of a ridge (around the dry spot): this algorithm takes into account gravity forces, surface tension, friction, and inertia effects. Simulation results performed by original method were compared with experiment and previous method that takes into account only gravity and capillary forces. It was demonstrated that both methods produce similar results at low Reynolds numbers. However, at Reynolds higher than one these two methods give different results. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Abstract Mathematical simulation of isothermal film flow for a viscous ponderous capillary liquid with dry spots on a solid substrate was performed. The algorithm was developed for calculation of the shape of a ridge (around the dry spot): this algorithm takes into account gravity forces, surface tension, friction, and inertia effects. Simulation results performed by original method were compared with experiment and previous method that takes into account only gravity and capillary forces. It was demonstrated that both methods produce similar results at low Reynolds numbers. However, at Reynolds higher than one these two methods give different results.
