• Energy conservation equation in integral form has been derived from first principles. Validity is demonstrated for flame wall interaction (FWI) a turbulent boundary layer. Wall heat transfer during FWI intrinsically related to the burning velocity. An of energy principle low Mach number conditions statistically steady premixed flame-wall within layers. The validity this based on three-dimensi...

The purpose of the study was to experimentally test performance four types wall-mounted mechanical ventilation exhaust air outlet devices. A full-scale mock-up a segment an external wall with constructed. tested devices include gravity louver, fixed-blade louver plate, and nozzle. assessment included two experiments over airflow rate range 25–94 l/s at isothermal conditions no influencing wind:...

Volumetric techniques were employed to study the adsorption of CO2 on a purified multi-wall carbon nanotubes (MWNT’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 K and pressures ranging from 30 to 150 kPa. Langmuir, Freundlich and Sips equations were used to represent the isotherms. Also the parameters of these fitted isotherm models have been determined. The ...

The data for the nonisothermal and isothermal thermal decompositions of lanthanum oxalate have been analysed using model-free model-fitting kinetic techniques. When applied to Coat-Redfern(CR) equation, widely used approach that results excellent fitting both but produces very ambiguous values Arrhenius parameters. These cannot be compared those obtained from experiments. On other hand, strateg...

The statistical behaviors of mean enstrophy and its evolution during head-on interaction premixed flames propagating toward a chemically inert flat wall across the turbulent boundary layer have been analyzed using direct numerical simulations for friction velocity-based Reynolds number [Formula: see text]. dynamics both isothermal adiabatic thermal conditions. contributions vortex-stretching vi...

The present article serves the purpose of pursuing Geometrization of heat flow on volumetrically isothermal manifold by means of RF approach. In this article, we have analyzed the evolution of heat equation in a 3-dimensional smooth isothermal manifold bearing characteristics of Riemannian manifold and fundamental properties of thermodynamic systems. By making use of the notions of various curva...

Abstract The chemical composition, structural and plastometric properties of different-ranked coals from Mongolia deposits were studied. non-isothermal iso-conversion Ozawa–Flynn–Wall Friedman model-free methods used to assess kinetic parameters differentiate decomposition steps. Key peculiarities the pyrolysis kinetics brown bituminous revealed discussed in terms composition properties. Brown ...

The problem of double-diffusive natural convection of Al2O3 -water nanofluid in a porous triangular enclosure in presence of heat generation has been studied numerically in this paper. The bottom wall of the cavity is heated isothermally, the left inclined wall is non-isothermal and the right inclined wall is considered to be cold. The concentration is higher at bottom wall, lower at right incl...
