Abstract: This article addresses the Cattaneo–Christov heat flux, radiation and joule heating model as applied to a Blasius–Rayleigh–Stokes flow through a transitive magnetic field. The mathematical models are converted into a pair of self-similarity equations by applying appropriate transformations. The reduced similarity equivalences are then solved numerically by the Runge–Kutta–Fehlberg 45th-order method. To better perceive the problem, the flow and energy transfer characteristics are explored for distinct values of different factors. From this analysis we found that Higher values of Q increase the f′η field and its interrelated thickness of the boundary layer. The temperature of the fluid and its interrelated layer thickness enhances for boost up values ofγ . Also found that the streamline graphs are dominant for Q=2 when compared with Q=0.5. The presence of Q has more impact on the results when compared to the case where Q is absent. The local RexCfx and NuxRex−12 scale back for increasing values of ω.
