. The present paper contains the computational estimations of the magnetized particulate flow of a tangent hyperbolic fluid due to the linearized stretching of the porous sheet under consideration of time dependency. Heat flow is affected by heat generation/absorption with the mediation of variable thermal conductivity and convective boundary conditions. According to the modeling of particulate flow, separate PDEs for fluid and particles are modeled. The assistance of the boundary layer approximation and appropriate transformations convert these PDEs into nonlinear ODEs and corresponding conditions. Approximate results are generated with the help of the numerical technique bvp4c. Upshots of emerging parameters such as unsteadiness parameter, magnetic parameter, Biot number, etc., of the present study are elaborated with the support of graphs and numeric values.
