In this study, a thermal-diffusive model using sinusoidal function for the oscillation term is presented. The employed to evaluate pulsating behavior in premixed counterflow flame fed with biomass particle cloud considering Lewis number and thermal radiation effects. order scrutinize characteristics of flame, time-related governing equations are written assumed multi-zone system analytically solved utilizing Matlab Mathematica software. To enforce continuity, suitable matching conditions temperature heat flux at interfaces derived. Time-dependent burning velocity, temperature, front position, reactants mass distributions presented, taking into account effective number, radiation, strain rate influences. An acceptable comparison numerical simulations affirms reliability mathematical procedure. obtained results indicated that instability biomass-fueled flames arrangements significantly relevant not only but also transferred from reaction zone unburnt reactants. Furthermore, it found flames, rate, addition can be key controlling individual modes.

Alloys are used in a wide variety of contexts, including aircraft building, the military, industry, medicine, and manufacturing. tools, equipment, cars, structures. Furniture, shipping containers, medical supply storage containers among products that benefit from usage aluminium alloys. To further enhance simultaneous heat transmission, scientists have developed nano-fluids, which essentially nano-particle suspensions regular fluid. Ferric Sulfate may be added to soil improve its quality is also clean water. Iron (3+) sulphate an iron (III) sulfate combination with 3:2 ratio ions. As catalyst, mordant, astringent, it serves several purposes. It metal molecule iron. Due these purposes, we employ K-K model study how alloys nanoparticles affect surface flow transfer. By making use boundary layer approach assumptions, partial differential equations (PDEs) were generated by approximating Navier-Stokes equation. This system transformed into ordinary (ODE's) using similarity transformations. Using BVP4C method, non-dimensions defined. Mathematical pictorial explanations provided for consequences key physical variables. founded magnitude temperature field directly proportional R value; higher value indicates more conduction liquid. Additionally, velocity fluid lessened impact melting effect.

This paper presents a numerical simulation of the mixed convective boundary layer (BL) motion bio-rheological liquid over an inclined plate under viscous dissipation and Joule heating effects. is significant because various applications electro-osmotic force, plates, viscoelastic fluids in biochemical engineering industrial domains. Furthermore, BL flow controlled by electromagnetic force (EMF). In this study, non-Newtonian model, called Jeffrey fluid was employed. ology: The rheological equations current study are nonlinear partial differential (PDEs). By applying set similarity transformations, these PDEs become coupled ordinary (ODEs), which then solved numerically using NDSolve method realistic constraints. Numerical solutions for velocity profile , temperature distribution skin friction (shearing stress), Nusselt number (heat transfer rate) were obtained subject to These outcomes dependent on 12 embedded parameters: Hartmann time relaxation parameter inclination with horizontal line convection Prandtl Brinkman suction/blowing slip thermal . authors discussed how variables affect features through graphs tables. liquids also discussed, compared liquid. enhancements largely parameter, number, number.
