Abstract :This paper presents an appropriate title that reflects the mathematical model of the above paper. Correct solutions for velocity and skin friction variables are presented for the given mathematical model of the above paper. The corresponding numerical results for the velocity and skin friction are shown graphically.The above paper investigates a closed form solution for the transient free convection flow of a viscous incompressible fluid between 2 infinite vertical parallel plates in the presence of radiation. The flow is set up due to free convective currents occurring as a result of application of constant heat flux at one wall and constant temperature on the other wall. The Rosseland approximation is used to describe the radiative heat flux in the energy equation. The governing partial differential equations are solved exactly using the Laplace-transform technique. The problem is interesting and challenging. However, there are errors in the above paper insert ignore into journalissuearticles values(Chaudhary and Jain, 2007);, which are presented as below
