Active Control of the Onset of Convection in Porous Medium by Mechanical Vibration,weakly nonlinear stability analyses have been developed by Gresho and Sani [.], Clever . [.] and by the Russian workers Gershuni and Lyubimov [.]. As shown by these studies, the Rayleigh number for the onset of synchronous convection increases with the frequency of vibration for a layer oscillatingBlemish 发表于 2025-3-23 16:50:28

Nonlinear Vortex Instabilities in Free Convective Boundary Layers in Porous Media,n becomes valid only at sufficiently large distances from the leading edge. If the heated surface is upward-facing, then instability of the flow takes the form of longitudinal vortices, and these form at a critical distance from the leading edge which is dependent on the inclination of the surface a消息灵通 发表于 2025-3-24 02:25:27
Thermal Non-Equilibrium Free Convection in a Cavity Filled With a Non-Darcy Porous Medium,olid structure are assumed to be in local thermal equilibrium. This assumption is satisfactory for small-pore media such as geothermal reservoirs and fibrous insulations and small temperature differences between phases. In the second kind of approach, the fluid and solid structure are assumed to be做事过头 发表于 2025-3-24 08:15:26
Entropy Generation for Free and Forced Convection in a Porous Cavity and a Porous Channel,The theories of reversibility and irreversibility are important in thermodynamics and crucial to the exergy method. Understanding the nature of irreversibility and how to minimise them in practice is essential for an engineering thermodynamicist. Contemporary engineering thermodynamics uses the rate生命 发表于 2025-3-24 13:04:48
Natural Convection in Anisotropic Heterogeneous Porous Medium,This phenomena, occurs through porous media in many systems and in nature, including the disposal of waste material, groundwater contamination, chemical transport in packed-bed reactors, food processing, etc. Double-diffusion may exhibit unsteadiness and complex flows patterns, bifurcations, etc., s柱廊 发表于 2025-3-24 17:50:49
