6.2.1Peclet number ThePeclet number(Pe) is dimensionless, representing the ratio of heat transfer by the motion of a fluid to the heat transfer bythermal conduction. Alternately stated, the Peis the ratio of heatflow rateby conduction under a unit temperature gradient and through a thickness in...
The application of the Nusselt number (Nu) correlation of a packed bed of spherical particles overestimates the rate of heat transfer in the packed beds of shredded materials. This is due to the dependence of flow distribution on the particle geometry. This discrepancy is even more pronounced ...
Péclet Number a dimensionless number that is a similarity criterion for processes of convective heat exchange; named after the French physicist J. C. Péclet (1793–1857). The Péclet numberPe=vl/a=Cpρvl/γ, wherelis the characteristic linear dimension of the surface of heat exchange,vis the...
The Péclet number is a dimensionless number used in calculations involving convective heat transfer. ...

The Reynolds number and equivalence ratio strongly influenced this first phase. It was followed by a second, longer phase, where temperature reached an intermediate value near 1000℃ that exhibited little sensitivity to Reynolds number and equivalence ratio. In a third phase, combustion was completed...
Heat transfer and mass transfer with heat generation in drops at high Peclet number. Kronig and Brink published a classic analysis of transport from translating droplets. Their analysis assumed that the bulk of the resistance to transfer wa... Souccar,Adham. - The University of Toledo. 被引量...

There we made the assumption that the axial heat conduction within the fluid can be ignored. This assumption implies that the Peclet number (Pe D = Re D Pr) = for the problem under consideration has to be large enough. If one neglects the axial heat conduction term in the energy ...
