“…This work has been extended by considering the mass transfer and chemical reaction effects (see Mahanthesh, Gireesha and Gorla, 2016). Later on, some innovative studies on nanoliquids with various physical aspects were carried out by several researchers (see Mahanthesh, Gireesha, Gorla, Abbasi and Shehzad, 2016; Makinde and Animasaun, 2016; Hussain et al ., 2018; Sheikholeslami and Shehzad, 2017; Mahanthesh, Gireesha and Athira, 2017; Muhammad, Alsaedi, Shehzad and Hayat, 2017; Animasaun, 2016; Sandeep et al ., 2017; Koriko et al ., 2017; Muhammad, Alsaedi, Hayat and Shehzad, 2017; Sheikholeslami et al ., 2017, 2018; Hayat, Khan, Waqas, Alsaedi and Farooq, 2017; Hayat et al ., 2016; Hayat, Qayyum, Alsaedi and Ahmad, 2017; Qayyum et al ., 2017a, b, 2018; Waqas et al ., 2017, 2018; Hayat, Waqas, Alsaedi, Bashir and Alzahrani, 2017; Hayat, Khalid, Waqas and Alsaedi, 2018; Hayat, Naz, Waqas and Alsaedi, 2018; Animasaun et al ., 2018; Sahu and Mahanthesh, 2018; Kumar et al ., 2018; Gireesha et al ., 2018; Mahanthesh, Gireesha, PrasannaKumara and Shashikumar, 2017).…”

Purpose The study of novel exponential heat source (EHS) phenomena across a flowing fluid with the suspension of nanoparticles over a rotating plate in the presence of Hall current and chemical reaction has been an open question. Therefore, the purpose of this paper is to investigate the impact of EHS in the transport of nanofluid under the influence of strong magnetic dipole (Hall effect), chemical reaction and temperature-dependent heat source (THS) effects. The Khanafer-Vafai-Lightstone model is used for nanofluid and the thermophysical properties of nanofluid are calculated from mixture theory and phenomenological laws. The simulation of the flow is also carried out using the appropriate values of the empirical shape factor for five different particle shapes (i.e. sphere, hexahedron, tetrahedron, column and lamina). Design/methodology/approach Using Laplace transform technique, exact solutions are presented for the governing nonlinear equations. Graphical illustrations are pointed out to represent the impact of involved parameters in a comprehensive way. The numeric data of the density, thermal conductivity, dynamic viscosity, specific heat, Prandtl number and Nusselt number for 20 different nanofluids are presented. Findings It is established that the nanofluid enhances the heat transfer rate of the working fluids; the nanoparticles also cause an increase of viscous. The impact of EHS advances the heat transfer characteristics significantly than usual thermal-based heat source (THS). Originality/value The effectiveness of EHS phenomena in the dynamics of nanofluid over a rotating plate with Hall current, chemical reaction and THS effects is first time investigated.

“…Shoaib et al [10] studied the three-dimensional rotating flow of magneto-hybrid nanofluid past an extendable surface with thermal radiation. Some illustrious research articles highlighting the novel features of thermal radiation can be seen in references [11][12][13][14][15][16][17][18]. In addition, the inclusion of heat generation/absorption is important in controlling the heat transport rate in several industrial processes such as in glass fibre production, hot rolling, endothermic reactions, paper production, heat conversation due to nuclear fuel wastage, etc.…”

In this research study, numerical and statistical explorations are accomplished to capture the flow features of the dynamics of ethylene glycol-based hybrid nanofluid flow over an exponentially stretchable sheet with velocity and thermal slip conditions. Physical insight of viscous dissipation, heat absorption and thermal radiation on the flow-field is scrutinized by dissolving the nanoparticles of Molybdenum disulphide (MoS2) and graphene into ethylene glycol. The governing mathematical model is transformed into the system of similarity equations by utilizing the apt similarity variables. The numerical solution of resulting similarity equations with associated conditions are obtained employing three-stages Lobatto-IIIa-bvp4c-solver based on a finite difference scheme in MATLAB. The effects of emerging flow parameters on the flow-field are enumerated through various graphical and tabulated results. Additionally, to comprehend the connection between heat transport rate and emerging flow parameters, a quadratic regression approximation analysis on the numerical entities of local Nusselt numbers and skin friction coefficients is accomplished. The findings disclose that the suction and thermal radiation have an adverse influence on the skin friction coefficients and heat transport rate. Further, a slight augmentation in the thermal slip factor causes a considerable variation in the heat transport rate in comparison to the radiation effect.

In the present era, nanofluids are one of the most important and hot issue for scientists, physicists, and mathematicians. Nanofluids have many important and updated characteristics compared to conventional fluids. The thermal conductivity, thermal expansion, and the heat transfer rate of conventional fluids are not up to the mark for industrial and experimental uses. To overcome these deficiencies, nanoparticles have been dispersed into base fluids to make them more efficient. The heat transfer characteristics through symmetry trapezoidal-corrugated channels can be enhanced using nanofluids. In the present article, a literature survey has been presented for different models of nanofluids and their solutions—particularly, exact solutions. The models for hybrid nanofluids were also mentioned in the present study. Furthermore, some important and most used models for the viscosity, density, coefficient of thermal expansion, coefficient of mass expansion, heat capacitance, electrical conductivity, and thermal conductivity are also presented in tabular form. Moreover, some future suggestions are also provided in this article.
