Effects of Reynolds number on the heat transfer characteristics a long (heated) equilateral triangular cylinder are investigated for range conditions Re = 50–150 (in steps 10) and Prandtl 0.71 (air) in unconfined unsteady cross-flow regime. In order to simulate present situation, computational grid is created by using commercial generator GAMBIT numerical computations carried out FLUENT (6.3). The SIMPLE method used solve continuity, Navier-Stokes energy equations along with appropriate...

Abstract The heat transfer in power‐law fluids across three corrugated circular cylinders placed a triangular pitch arrangement is studied computationally confined channel. Continuity, momentum, and energy balance equations were solved using ANSYS FLUENT (Version 18.0). flow assumed to be steady, incompressible, two‐dimensional, laminar. A square domain of side 300 D h selected after detailed study. An optimized grid with 98,187 cells used the convergence criteria 10 −7 for continuity, x...

Abstract Using the theory for propagation of wavefronts defined by weak discontinuities, paper presents an analysis shock wave formation in a two‐dimensional steady supersonic flow over concave corner radiative magnetogasdynamics. Transport equations are derived which lead to determination distance and also conditions ensure that no will ever evolve on front. It is assessed as how influenced (i) presence magnetohydrodynamic effects, (ii) initial curvature wall, (iii) upstream Mach number.

Abstract Background Despite higher incidence of patellofemoral pain (PFP) and consequently morbidity, the understanding about PF factors leading to arthritis is way lacking. Material Methods A prospective study first 80 patients who were diagnosed with chondromalacia patella (CMP) on magnetic resonance imaging (MRI) divided into early late CMP groups evaluated clinically, radiologically, in terms functional outcome.

Abstract A differential approximation for the equations of radiative transfer in a grey gas arbitrary opacity including effects flux, pressure and energy density is applied study thermal radiation on growth decay properties finite amplitude waves shape propagating through thermally inviscid gas.

Introduction A NUMBER of problems relating to wave propagation through ideal fluids or with internal relaxation, which are in a constant state at rest before the arrival front, have been considered previously (a short account is given by Becker and Clarke McChesney). But much less interest has shown waves nonuniform atmospheres, exceptions being work Srinivasan Vincenti Clarke.' The present Note applies theory characteristics study behavior plane, cylindrical, spherical heads propagating...

Abstract The computational study of power‐law fluid flow, along with heat transfer attributes over a corrugated heated cylinder, is explored using ANSYS FLUENT (Version 18.0). Fluids indices fall in the range 0.25 ≤ n 1.5, and Reynolds number spans 1 Re N 40. flow two‐dimensional, steady, laminar.

Quantum effects on the Rayleigh−Taylor instability in an inhomogeneous stratified incompressible, viscoelastic Walters' (model B') fluid/plasma through a porous medium are investigated. The linear growth rate is derived for case where plasma with exponential density, viscosity, viscoelasticity, and quantum parameter distribution confined between two rigid planes at z = 0, h. solution of linearized equations system together boundary conditions leads to derive dispersion relation (the...

Abstract Objectives / Scope In a lifespan of gas well multiphase flow regime keeps changing. When rate falls below critical rate, loads up, significant reduction in occurs and eventually ceases to flow. Tripura Asset is operating nearly 100 wells most them experience liquid loading their production life, leading loss recovery. Many have experienced sharp decline due loading. The paper highlights integrated modelling approach adopted identify successful application deliquification techniques...
