Objectives: In this present framework, heat transfer of the thermal radiation effect on natural convection around a vertical permeable flat surface immersed in a saturated porous medium has been investigated by considering the thermal radiation effect. Methods: The governing partial differential equations of the considered problem are converted to the nonlinear ordinary differential equations over the infinite domain with the aid of similarity transformations. In order to analyze the thermal radiation, the Mu ̈ntz − Legendre wavelet operational matrix method has been considered to solve the corresponding nonlinear ordinary differential equation. Findings: To check the efficiency of the proposed strategy, the third-order nonlinear boundary value problem having the exact solution is considered a test problem. Also, the obtained findings are compared with the findings of the Haar wavelet operational matrix method. Novelty: The three physical parameters of temperature exponent λ thermal radiation Rd, and Injection/suction fm on vertical velocity and temperature profiles are demonstrated and discussed graphically. Also, the comparison ofthe Mu ̈ntz−Legendre wavelet operational matrix method results with Haar wavelet operational matrix method results ensure that the solutions obtained by Mu ̈ntz−Haar wavelet operational matrix method results.
