Abstract

The hybrid nanofluid turbulent convective migration within a tube having turbulator was analyzed using the numerical approach and investigated through entropy optimization principle. The forced convective fluid motion is modeled through coupled partial differential equations satisfying suitable boundary restrictions. The set of developed coupled equations is solved through ANSY Fluent Solver. The characteristics of the chosen hybrid nanomaterial were clarified via contours of streaming velocity, and temperature by varying the strength of Reynolds number (Re) and revolution (P) of tape. It is found that the exergy loss in the tube decreases with the increasing Re and P. The fluid velocity enhances with the augmenting Re associated with the higher input power and with the increasing P. The temperature declines with the augmenting fluid turbulence and drops (rises) with the augmenting P at bigger (smaller) Re. The exergy destruction with augmenting Re drops at much faster rate as compared with the enhancing P. The accommodation of the achieved results with the published work depicts reasonable correctness of the applied simulation procedure.
