WebRayleigh flow refers to diabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come into consideration, although the Rayleigh flow model certainly also applies to incompressible flow.For this model, the duct area remains constant and no mass is added within the duct. Therefore, … WebExpert Answer.

WebRayleigh flow refers to frictionless, non-Adiabatic flow through a constant area duct where the effect of heat addition or rejection is considered. Compressibility effects often come … WebIncreasing Rayleigh number beyond the critical value establishes a bulk motion within the enclosure. Owing to this departure from Boussinesq effects, this is accompanied by formation of hexagonal cells. However, if this deviation is trivial, the formed hexagonal cells will be replaced by two-dimensional rolls [35].Remaining steps in the flow transition …

WebRayleigh number significance: The significances of Rayleigh number are listed below, 1) The rayleigh number states the relation between grashof number and the Prandtl number. 2) Rayleigh number also helps to find the type of fluid flow, If Ra < 10^9, then the flow is laminar and If Ra > 10^9 then the flow is turbulent. WebNov 27, 2024 · As we have already seen, if, for a given mass flow rate, the heat added is equal to q^*, then the Mach number at the duct exit becomes 1. The duct is then said to be choked. Choking can happen in a flow due to several reasons. Since, in this case, the choking is due to heat addition, it is called thermal choking.
