Webdescribed by the diffusion equation. Convection is always present in fluid flow but its contribution to the momentum balance is neglected for creeping (low Reynolds number) flow or cases where the velocity is perpendicular to the velocity gradient. In this case 2, velocity perpendicular to velocity gradient p t ν ρ ∂∇ =−+∇ ∂ v fv. WebTheir dictionary meanings seem to exacerbate the situation: (convection) the transfer of heat through a fluid (liquid or gas) caused by molecular motion. (diffusion) The spreading of something more widely or the intermingling of substances by the natural movement of their particles. fluid-dynamics. terminology. inwi association

WebDec 23, 2016 · The equations that describe natural convection usually involve the momentum equation, the continuity equation, and the energy transport or mass transport equation. If buoyancy is driven by … WebFeb 2, 2011 · The flow may give rise to convective heat transfer where it is driven by a pump and is referred to as forced convection, or arise as a consequence of temperature gradients and buoyancy, referred to as natural or free convection. Examples are given later in this Section and are shown in Figure 1to facilitate introduction to terminology and concepts.
