This study investigates the effects of activation energy and chemical reactions on boundary layer flow around a wedge that is moving in nanofluid. To represent problem, nonlinear partial differential equations are utilized. These can be reduced to coupled ordinary using similarity transformations. numerically solved Keller Box technique, then their numerical pictorial solutions studied MATLAB. The looks at relationship between velocity, temperature, concentration profiles important factors such as Prandtl number, constant parameter, energy, reaction rate. parametric range 0.1 ≤ λ 1.0, Le 3.0, E 2.0, Pr 7.0, Nt 0.5, Nb σ 3.4, δ 2.5, β 2.0 Furthermore, comprehensive investigation conducted into remedies for skin friction heat transmission It deduced growing magnitude fluid velocity noted lower Prandtl, factor, greater energy. depicted maximum enhancing temperature with good distributions examined each pertinent factor. transport Lewis temperature-difference but increases pressure-gradient Brownian factor rise.

The importance of this investigation is to examine the heat and mass transportation magneto nanofluid movement along a heated sheet with exponential temperature-dependent density, entropy optimization, thermal buoyancy, activation energy, chemical reaction aspects. influence these factors in cutting tools by means machining lubrication significant process zone, chip cleaning, lubricating, cooling productivity milling. corresponding energy are essential understand behavior nanofluid. appropriate transformations used solve nonlinear partial differential equations within framework ordinary using stream functions similarity variables. Keller box method employed efficiently computationally under Newton–Raphson approach. Through tables figures, fluid velocity, temperature distribution, concentration consequences sketched various controlling parameters. It seen that function increases noticeable amplitude as Eckert factor, variable chemical-reaction, increase. found enhancement deduced for maximum Brownian motion thermophoresis. This work important applications such fluids, drilling, brake oil, engine minimum quantity lubrication, enhanced oil recovery, controlled friction between tool-chip tool-work during operations.
