• Heat transfer enhancement of kerosene–alumina nanofluid is studied.
• DTM is applied to solve the governing equations.
• Nu is an increasing function of Rd, ϕ.
• Be is a decreasing function of R, Ec.
A semi-analytical investigation is performed into the force convection heat transfer characteristics and entropy generation of kerosene–alumina nanofluid in a channel of semi cryogenic engine. Thermal radiation effect is considered in energy equation. The governing equations are reduced to ordinary equation by means of similarity solution and solve by Differential Transformation Method. Velocity, temperature and concentration profiles as well as the skin friction coefficient, Nusselt number and Bejan number are determined for different values of pertinent parameters such as Radiation parameter, nanofluid volume fraction, Viscosity parameter and Eckert number. Results indicate that entropy generation is an increasing function of Viscosity parameter and Eckert number while it is a decreasing function of Radiation parameter. Also it can be concluded that Nusselt number enhances with augment of Radiation parameter and nanofluid volume fraction while it decreases with increase of Radiation and Viscosity parameter parameters.
