Did you know?
WebThe product of Reynolds number and Prandtl number is known as Peclet number. Peclet number, Pe, is a dimensionless group representing the ratio of heat transfer by motion of a fluid to heat transfer by thermal conduction. WebI have seen the Peclet number written for mass transport as the product of the Schmidt and Reynolds number. Thus it could be written:- Pe = lv/D where D is some appropriate diffusion coefficient (or mass diffusivity). Its use is common in …
WebApr 16, 2024 · Peclet number: The product of the Reynolds number and Prandtl number is called Pecklet number. The Peclet number is a measure of the relative importance of advection versus diffusion. Or, the Peclet number may be interpreted as the ratio of the heat capacity rate of fluid in the boundary layer to axial heat conductance of the boundary layer. WebPeclet number, or officially known as Péclet number, is a dimensionless number that represents the ratio of advection and diffusion caused by heat transfer. It can be expressed in the following equation: where; Pe : Péclet number U : Characteristic speed [m/s] L : Characteristic length [m] α : Thermal diffusivity [m 2 /s]
WebQuestion: For heat transfer, the Péclet number can also be described as the product of the Reynolds number and Prandtl number. Give a brief definition of these numbers and describe the concept of combining them to get Péclet number in 2-3 sentences. Also discuss in 1-2 sentences the concept of turbulence in heat transfer, and why it does or does not apply to WebThe Péclet number is simply defined as the product of the Reynolds number, which describes the flow regime, and the Prandtl number, which describes the relationship …
WebSep 7, 2024 · In the chapter 3.2 Approximation of scalar convection-diffusion equations, you find at page 88 some notes on the Péclet number. You essentially get this dependence by applying Cea’s lemma. The assumption here is that you have a conforming finite element space. $\endgroup$ –
