In this research article, the electrically conducting magnetized radiative squeezed flow of two‐dimensional time‐dependent viscous incompressible flow between two parallel disks with heat source/sink and Joule heating effects under the presence of an unsteady homogeneous first order chemical reaction is demonstrated numerically. The considered physical problem is studied under the influence of Lorentz forces to describe the effect of an applied magnetic field. Heat dissipation due to viscosity and Joule heating are considered in the energy equation to demonstrate the behavior of the thermal profile. Also, the thermodynamic behavior of temperature field is described by considering the concept of heat source/sink in the energy equation. The mass transport characteristics of a viscous fluid are described through the time‐dependent chemical reaction of first order type with homogenous behavior. Thus, the considered physical problem gives the time‐dependent, highly nonlinear coupled partial differential equations, which are reduced to a system of ordinary differential equations by invoking the suitable similarity transformations. The discretized first order ordinary differential equations are solved by using the Runge‐Kutta fourth order integration scheme with the shooting technique (RK‐SM) and bvp4c Matlab function. Flow sensitivity of various emerging control parameters are described with the help of tables and graphs. The axial velocity field enhanced for the suction case and suppressed for the blowing case for the increasing values of suction/injection parameter. Also, an excellent comparison between the present solutions and previously published results shows the accuracy and validity of the present similarity solutions and used numerical methods.
