The study examines two aqueous‐based combinations: one with single‐wall nanotubes (SWCNTs) other multi‐WCNTs (MWCNTs). choice these is owing to their amazing characteristics including feather‐weight, remarkable thermal electrical conductivities, chemical mechanical steadiness. These flows are influenced by variable nonuniform source/sink effects radiation. Furthermore, analysis incorporates distinct homogeneous‐heterogeneous (h‐h) reactions. novel unsupervised Morlet wavelet neural networks (MW‐NNs), combined heuristic algorithm, used solve nonlinear ordinary differential equations (ODEs). MW function transforms ODEs into artificial NNs‐based fitness then particle swarm optimization (PSO) for optimal values. weights MW‐NNs optimized using PSO within range −10 10.
