Mathematical modeling and numerical simulation of natural convection of thermal comfort inside the building
Publication details: Prayagraj Pushpa Publishing House 2022Edition: Vol.30, DecDescription: 205-218pSubject(s): Online resources: In: JP journal of heat and mass transferSummary: We conduct a numerical and mathematical study of a phenomenon of natural internal convection in an enclosure heated simultaneously by a constant flow, namely thermal comfort in winter. This study simulates the case of heat generation in a building. We see well that the considered model governs the equation of continuity, momentum and energy. These equations are written in dimensionless terms of primitive variables and are redone in general form. Usually, these equations do not admit analytical solutions, so resorting to numerical methods is mandatory. We have opted to use the double scan method. The control parameters are the numbers of Rayleigh (0 < Ra < 105) and of Prandtl (Pr = 0.71). Indeed, the results which we attained are in perfect agreement with those attained by other authors working in the same field.| Item type | Current library | Status | Barcode | |

We conduct a numerical and mathematical study of a phenomenon of natural internal convection in an enclosure heated simultaneously by a constant flow, namely thermal comfort in winter. This study simulates the case of heat generation in a building. We see well that the considered model governs the equation of continuity, momentum and energy. These equations are written in dimensionless terms of primitive variables and are redone in general form. Usually, these equations do not admit analytical solutions, so resorting to numerical methods is mandatory. We have opted to use the double scan method. The control parameters are the numbers of Rayleigh (0 < Ra < 105) and of Prandtl (Pr = 0.71). Indeed, the results which we attained are in perfect agreement with those attained by other authors working in the same field.
