Pressure work and viscous dissipation in the equations of thermal convection in a vertical channel Anthony Kay 2134/22423 https://repository.lboro.ac.uk/articles/journal_contribution/Pressure_work_and_viscous_dissipation_in_the_equations_of_thermal_convection_in_a_vertical_channel/9388736 Equations for fully developed flow in a vertical channel have been solved, taking into account viscous dissipation, and using formulations with and without pressure work. Perturbation solutions are used to distinguish the effects of viscous dissipation from pressure work. Viscous dissipation has very little effect on free convection flows driven by temperature differences or heat fluxes at the channel walls, but it may play a major role in forced convection. 2016-09-13 13:50:05 Pressure work Thermal convection Vertical channel Viscous dissipation Mechanical Engineering Mathematical Sciences not elsewhere classified
