To investigate enhanced heat transfer analysis on axisymmetric hydro-magnetic flow through contracting or expanding Darcy porous channels. The significance of the axisymmetric flow on MHD ternary hybrid nanofluid over a permeable channel that is both expanding and contracting the inspiration of thermal radiation is scrutinised in the current examination. To convert the PDEs into ODEs, suitable self-similarity transformations are utilised. After applying changes, we used the ODE45 technique for graphical purposes. The effect of active parameters affecting the fluid’s capacity to transfer significance is shown in graphs (3D, surface plots, and vector plots) tables, and we demonstrated on multilinear regression model (MLR) schemes. In this model, we considered (Sea water—Cu, MoS2, Al2O3/Ag, SWCNT, MWCNT) ternary hybrid nanofluid; this kind of combination plays a significant part in environmental control, thermal power plants and coastal manufacturing facilities. The numerical method ODE45 has been used in the present study by using MATLAB software. The acquired (R2 = 96.92%) R2 value indicates that the model was more accurate to fit the entire system. Case-1 (Sea water—Cu, MoS4, Al2O3) has a higher Nusselt number transfer rate than case-2 (Sea water—Ag, SWCNT, MWCNT).
