Mixed convection flow and heat transfer of chemically reactive drilling liquids with clay nanoparticles subject to radiation absorption
Abstract
Impact of radiation absorption on chemically reactive and heat generating drilling liquids comprising of water-clay, kerosene-clay or engineoil-clay nanofluids flowing through a vertical channel is considered. Applications are found in rig drilling process for the convective transport of constituent materials up to the surface by the fluid. It is presumed that the cold and hot parallel walls are maintained at different uniform temperatures, but with unequal slip factors. One of the slippery heated walls is stationary while the other stretches linearly. The partial differential equations are scaled to ordinary equations in tandem with the physical boundary conditions, and evaluated through homotopy perturbation method. Certification is accredited via data comparison with numerical results using shooting method. Among others, the results of this investigation suggest that the concentration and temperature distributions dip due to larger radiation absorption and viscosity parameters with or without the suction, velocity slips, and the chemical reaction parameters.
