Research ArticleOpen accessIn the keywordsEffect of Size of Heated Obstruction within Room on Three Dimensional Air Flow CharacteristicsAbduljabbar Muttair Ahmed, Mukhtar Ahmad, Abdur RahimProblem statement: This study reported a numerical investigation of three-dimensional turbulent buoyant recirculating flow within a room with heated obstruction. Approach: The study involved the solution of partial differential equations for the conservation of mass, momentum, energy, concentration, turbulent energy and its dissipation rate. These equations were solved together with algebraic expressions for the turbulent viscosity and the heat diffusivity, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 6,934 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHeat Generation/Absorption Effect on Natural Convection Flow in a Vertical Annulus with Time-Periodic Boundary ConditionsMichael O. Oni, Basant K. JhaThe role of heat generation/absorption on natural convection flow formation in a vertical annulus with prescribed time-periodic heating is investigated in this article. The governing continuity, momentum and energy equations are converted into ordinary differential equation using suitable transformations and closed form expressions are obtained for temperature distribution, velocity profile, Nusselt number, skin friction and mass flow rate in terms … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 27 Jul 2019 · 6,335 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCFD Simulation of Biogas Fired Clay Brick KilnAlemayehu Beyene, Venkata Ramayya, Getachew ShunkiMore strong and quality clay bricks are obtained if and only if bricks are fired with uniform optimum temperature during clay brick firing process in the clay brick kiln. To insure this transient temperature of fluegas and brick are analyzed using CFD simulation during clay brick firing in the clay brick kiln. In the simulation, 3-D geometrical model of fluegas … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 20 Jun 2018 · 8,799 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNumerical Investigation on Performance Improvement in Tube Inserted with Delta Winglets on Discrete Right-Angled Triangular PlatesAmnart Boonloi, Withada JedsadaratanachaiNumerical investigations on flow topology and heat transfer behavior in a round tube heat exchanger inserted with Delta Winglets (DW) on Discrete Right-angled Triangular Plates (DRTP) are performed. The influences of DW heights; b/D or BR = 0.05-0.25 and flow directions; DW with V-Downstream (DWVD) and DW with V-Upstream (DWVU), are studied for turbulent flow; Re = 3000-10,000. The finite … …Journal of Mathematics and Statistics, Vol. 13, Issue 1 · 16 Mar 2017 · 7,049 accessesView PDF Cite
