“…Sami Ullah Khan et al [ 18 ] and Imad Khan et al [ 19 ] studied the behavior of non-Newtonian fluids, specifically Eyring-Powell fluids, in flow over-stretching and flat plate surfaces. Prabhavathi et al [ 20 ], Sudarsana Reddy and Chamkha [ 21 ], and Swarnalathamma [ 22 ] simultaneously examined the phenomenon of free convection in nanofluids, taking into account the influence of MHD and chemical processes. Samuel Olumide Adesanya et al [ 23 ], Saima Noreen [ 24 ], and Abdul Samad Khan et al [ 25 ] conducted numerical investigations on non-Newtonian fluid flow with the influence of MHD and convective boundary conditions.…”

“…One of the effective techniques is using nanoparticles in working fluid (Chamkha and Rashad, 2012;Sözen et al, 2018;Sreedevi et al, 2020aSreedevi et al, , 2020b to prepare different nanofluids by mixing solid nano-sized particles in conventional fluids such as oil and water. Nanoparticles are also extensively used in different applications to enhance the overall performance of thermal systems (Prabhavathi et al, 2017;Sreedevi et al, 2018;Sreedevi and Reddy, 2019;Sreedevi and Reddy, 2021;Chamkha, 2017a, 2017b). Basically, Nanofluids are considered as a mixed fluid in which nanoparticles (nanometer-sized particles) are mixed in the base working fluid to improve heat transfer (A gbulut and Sarıdemir, 2019;Reddy and Chamkha, 2018).…”

Purpose Using suspended nanoparticles in the base fluid is known as one of the most efficient ways for heat transfer augmentation and improving the thermal efficiency of various heat exchangers. Different types of nanofluids are available and used in different applications. The main purpose of this study is to investigate the effects of using hybrid nanofluid and number of plates on the performance of plate heat exchanger. In this study, TiO2/water single nanofluid and TiO2-Al2O3/water hybrid nanofluid with 1% particle weight ratio have been used to prepare hybrid nanofluid to use in plate type heat exchangers with three various number of plates including 8, 12 and 16. Design/methodology/approach The experiments have been conducted with the aim of examining the impact of plates number and used nanofluids on heat transfer enhancement. The performance tests have been done at 40°C, 45°C, 50°C and 55°C set outlet temperatures and in five various Reynolds numbers between 1,600 and 3,800. Also, numerical simulation has been applied to verify the heat and flow behavior inside the heat exchangers. Findings The results indicated that using both nanofluids raised the thermal performance of all tested exchangers which have a various number of plates. While the major outcomes of this study showed that TiO2-Al2O3/water hybrid nanofluid has priority when compared to TiO2/water single type nanofluid. Utilization of TiO2-Al2O3/water nanofluid led to obtaining an average improvement of 7.5%, 9.6% and 12.3% in heat transfer of heat exchangers with 8, 12 and 16 plates, respectively. Originality/value In the present work, experimental and numerical analyzes have been conducted to investigate the influence of using TiO2-Al2O3/water hybrid nanofluid in various plate heat exchangers. The attained findings showed successful utilization of TiO2-Al2O3/water nanofluid. Based on the obtained results increasing the number of plates in the heat exchanger caused to obtain more increment by using both types of nanofluids.

This work analyzes the unsteady two-dimensional nanofluid flow over a vertical stretching permeable surface in the presence of an inclined magnetic field and nonuniform heat source/sink. Four different types of nanoparticles, namely silver Ag, copper Cu, alumina Al 2 O 3 , and titania TiO 2 , are considered by using water as a base fluid with the Prandtl number Pr = 6.785. The governing partial differential equations are transformed to coupled non-linear ordinary differential equations by appropriate similarity transformation. Furthermore, the similarity equations are solved numerically by using the fourth-order Runge-Kutta integration scheme with Newton Raphson shooting method. A comparison of obtained numerical results is made with previously published results in some special cases, and excellent agreement is noted. Numerical results for velocity and temperature profiles as well as skin friction coefficient and local Nusselt number are discussed for various values of physical parameters. It tends to be discovered that, the magnetic field inclination angle γ has the capability to strengthens the magnetic field and reduce the velocity profile of the flow. Also, it can be found that, by using various types of nanofluids, velocity and temperature distributions change, which means that the nanofluids are important in the cooling and heating processes. The thermal boundary layer thickness is related to the increased thermal conductivity of different types of nanofluids, i.e., the minimum (maximum) value of the temperature is obtained by adding titanium oxide (silver) to the fluid as the nanoparticles.
