Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This work discusses the thermal performance of magnetized hybrid nanofluid flow over a variable porous stretchable surface, emphasizing the underlying physical mechanisms governing heat and mass transfer. The Cattaneo–Christov flux model is used in place of Fourier's and Fick's laws to incorporate relaxation effects, ensuring a more realistic ...

Journal of Applied Polymer Science, EarlyView.Cooling holes provide a simple passive cooling strategy for polymer spur gears, reducing maximum operating temperature by up to 9.39% while introducing a measurable gear mesh stiffness penalty. A validated response‐surface model reveals how hole size and location govern this thermal–mechanical trade‐off, enabling design optimization for thermally and ...

Journal of Applied Polymer Science, EarlyView.This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...
