Flow and heat distribution over a convergent or divergent channel plays a major role in aeronautical, pharmaceutical, dynamic, civil, climatic, and biomechanical engineering, as well as heat transfer through a porous medium, has piqued the interest of researchers due to its numerous aerospace and automotive manufacturing, including waste disposal, raw petroleum products, grain collection, porous coating, petroleum lagoons, groundwater pollution, packed-bed power plants etc. Further, addition of nanoparticles to base liquid will improve the thermal distribution. Based on the above affordable application the present study will focus on heat transfer enhancement in ternary nanofluids flows induced by stretched convergent or divergent channels. The mobility of ternary nanoparticles occurs in the porous zone. The uniform energy absorption and generation influence is included in the energy expression. Through the use of comparable variables, the flow expressions are transformed into a system of non-linear ODEs (ordinary differential equations). To tackle the problem, the Runge-Kutta-Fehlberg fourth and fifth order (RKF-45) scheme with shooting procedure is adopted. The nature of imposing limitations on physically significant quantities is explored and carried out. The augmentation in solid volume-fraction of both stretched/shrinked channels resulted a reduction in temperature. Furthermore, it is found that the increasing heat sink or source factor and Eckert number augmented the rate of energy transport in the diverging channel, but reverse nature is found in the converging channel. It is also noticed that the ternary nanofluid has a greater impact than the hybrid and mano-nanofluid.

Applications: The interaction of nanoparticles and base solvents of different nature attained much interest of the researchers in the recent time. These use in medication, detection of cancer cells, applied thermal engineering, and electrical and mechanical engineering. Among the broad range of applications, investigation of nanofluid through converging/diverging channel is important which is of much interest in the field of medical sciences. Purpose and methodology: The core purpose of this study is to introduce a new heat transfer model for two natures of nanofluids with bi host solvents. The model in hand achieved through nanofluid expressions, similarity equations and induction of novel dissipation effects. At later stage, numerical treatment is performed to explore the actual behaviour of nanofluids inside the oblique walls which is very important. Core findings: From the drawn results, it is found that the motion could be controlled by expanding the channel walls ([Formula: see text]) and high Re and in Al2O3-H2O it is optimum. The nanofluids based on Al2O3 and C2H6O2 have much ability to transmit heat than the other nanofluids. Moreover, dissipation effects ([Formula: see text]) played significant role and boosted the temperature while keeping [Formula: see text] and [Formula: see text], respectively. Also, the study is validated and achieved good agreement between existing and the current study.

“…Improving the thermal energy transport coefficient in forced convection flow inside channels is an area that has long piqued the interest of heat transfer (HT) experts because of the important industrial applications of channel flows. So far, various methods have been proposed by researchers, including the use of grooves, ribs, and turbulators [1][2][3][4][5][6][7][8], as well as magnetic field and electric field [9][10][11][12][13][14][15]. The dimensions, type of working fluid, and arrangement of flow in the exchanger are among the important factors for the performance of heat exchangers.…”

The capabilities of nanofluids in boosting the heat transfer features of thermal, electrical and power electronic devices have widely been explored. The increasing need of different industries for heat exchangers with high efficiency and small dimensions has been considered by various researchers and is one of the focus topics of the present study. In the present study, forced convective heat transfer of an ethylene glycol/magnesium oxide-multiwalled carbon nanotube (EG/MgO-MWCNT) hybrid nanofluid (HNF) as single-phase flow in a heat exchanger (HE) with elliptical corrugated tubes is investigated. Three-dimensional multiphase governing equations are solved numerically using the control volume approach and a validated numerical model in good agreement with the literature. The range of Reynolds numbers (Re) 50 < Re < 1000 corresponds to laminar flow. Optimization is carried out by evaluation of various parameters to reach an optimal case with the maximum Nusselt number (Nu) and minimum pressure drop. The use of hybrid nanofluid results in a greater output temperature, a higher Nusselt number, and a bigger pressure drop, according to the findings. A similar pattern is obtained by increasing the volume fraction of nanoparticles. The results indicate that the power of the pump is increased when EG/MgO-MWCNT HNFs are employed. Furthermore, the thermal entropy generation reduces, and the frictional entropy generation increases with the volume fraction of nanoparticles and Re number. The results show that frictional and thermal entropy generations intersect by increasing the Re number, indicating that frictional entropy generation can overcome other effective parameters. This study concludes that the EG/MgO-MWCNT HNF with a volume fraction (VF) of 0.4% is proposed as the best-case scenario among all those considered.
