A steady flow of carbon nanotubes (CNTs) nanofluids and heat transfer past a horizontally moving thin needle are investigated under the influence magnetohydrodynamic (MHD). Single-walled CNTs (SWCNTs) multi-walled (MWCNTs) two main nanoparticles that represent CNTs. The slender moves relative to with parallel velocity in either same or opposite direction. Using similarity method, system partial differential equations (PDEs) subject boundary conditions is converted into nondimensional ordinary (ODEs). ODEs then reduced first-order solved using MATLAB R2022b bvp4c solver. On numerical scale, impacts varying potential parameters, such as magnetic, CNTs' volume fraction, on temperature profiles, skin friction, coefficients investigated. Utilising response surface methodology (RSM), optimisation based experimentation physical quantities performed. outcomes depicted tables graphical approach. Results indicate existence dual solutions when travels Moreover, increase magnetic parameter by 100% will both friction nearly 30% 4%, respectively. Furthermore, value fraction increases 100%, rate substantially almost 33%. However, doubling size can significantly reduce coefficient 32%. RSM results demonstrate maximal generated at highest values parameters lowest parameter. Findings also show SWCTNs superior MWCNTs coefficients. When comparing performance water kerosene, we find less effective base fluid than kerosene.

ABSTRACT Engineers and researchers in the field of thermal analysis are searching for novel approaches to boost their performance by enhancing characteristics electrical equipment. Non‐Newtonian fluids used technical industrial settings owing high conductivity. In connection with this, present study investigates fluid flow heat transmission a hybrid nanomaterial (carbon nanotubes ferric oxide) over curved surface. The originality this is related examining impact generation nonlinear radiation convective boundary conditions Sakiadis (SF) Blasius (BF). system mathematical relations partial differential equation form changed an ordinary (ODE) using appropriate variables. indeterminate ODEs were solved ODE analyzer, which accessible computer software Maple. graphs demonstrate importance critical factors concerning velocity temperature fields. SF has thinner layer than BF, results more pronounced drop. effects altering physical parameters on Nusselt number optimized through response surface methodology BF SF. affected effects, but shows increased sensitivity wall gradients, indicating distinct optimization each scenario. every situation, nanofluid multiwall carbon oxide exhibits excellent performance. To validate chosen numerical approach, tabular description provided generate comparison.
