Adding small particles into a fluid in cooling and heating processes is one of the methods to increase the rate of heat transfer by convection between the fluid and the surface. In the past decade, a new class Of fluids called nanofluids, in which particles of size 1-100 nm with high thermal conductivity are Suspended in a conventional heat transfer base fluid, have been developed. It has been shown that nanofluids containing a small amount of metallic or nonmetallic particles, Such as Al2O3, CuO, Cu, SiO2, TiO2, have increased thermal conductivity compared with the thermal conductivity of the base fluid. In this work, effective thermal conductivity models of nanofluids are reviewed and comparisons between experimental findings and theoretical predictions are made. The results show that there exist significant discrepancies among the experimental data available and between the experimental findings and the theoretical model predictions.

Numerical analysis of laminar forced convection with temperature-dependent thermal conductivity of nanofluids and thermal dispersion
Özerinç, Sezer; Kakac, S. (2012-12-01)
Nanofluids are promising heat transfer fluids due to their high thermal conductivity. In order to utilize nanofluids in practical applications, accurate prediction of forced convection heat transfer of nanofluids is necessary. In the first part of the present study, we consider the application of some classical correlations of forced convection heat transfer developed for the flow of pure fluids to the case of nanofluids by the use of nanofluid thermophysical properties. The results are compared with experi...
NUMERICAL ANALYSIS OF CONVECTIVE HEAT TRANSFER OF NANOFLUIDS FOR LAMINAR FLOW IN A CIRCULAR TUBE
Kirez, Oguz; Güvenç Yazıcıoğlu, Almıla; KAKAÇ, SADIK (2012-11-15)
In this study, a numerical analysis of heat transfer enhancement of Alumina/water nanofluid in a steady-state, single-phase, laminar flow in a circular duct is presented for the case of constant wall heat flux and constant wall temperature boundary conditions. The analysis is performed with a newly suggested model (Corcione) for effective thermal conductivity and viscosity, which show the effects of temperature and nanoparticle diameter. The results for Nusselt number and heat transfer enhancement are prese...
Performance analysis of grooved heat pipes using 3-D multi-channel thermal resistance network
Sezmen, Ramazan Aykut; Dursunkaya, Zafer; Çetin, Barbaros; Department of Mechanical Engineering (2021-9)
Heat pipes are phase change heat transfer devices that transfer high amounts of heat with low temperature differences compared to conventional cooling techniques due to their high thermal conductivity. Since heat pipes do not require any external power supply and not involve any moving parts, they are preferred for high reliability applications and in wide range of industrial applications from thermal management of electronics to space applications. Essentially, heat pipes use the advantage of occurring pha...
HEAT TRANSFER ENHANCEMENT IN LAMINAR CONVECTIVE HEAT TRANSFER WITH NANOFLUIDS
Özerinç, Sezer; YAZICIOGLU, A. G. (2011-06-03)
In order to utilize nanofluids in practical applications, accurate prediction of forced convection heat transfer of nanofluids is necessary. In the first part of the present study, we consider the application of some classical correlations of forced convection heat transfer developed for the flow of pure fluids to the case of nanofluids by the use of nanofluid thermophysical properties. The results are compared with experimental data available in the literature, and it is shown that this approach underestim...
Gradient-based optimization of micro-scale pressurized volumetric receiver geometry and flow rate
Akba, Tufan; Baker, Derek Keıth; Mengüç, M. Pınar (2023-02-01)
This study focuses on the design optimization of a micro-scale pressurized volumetric receiver by changing geometry and flow rate constrained by the volume, outlet air temperature, and outer surface temperature. The pressurized volumetric receiver model is replicated from an existing model, which assumes constant air pressure and neglects the convection loss from the cavity. The existing model is revised from a solver to a design optimizer. The replicated model is restructured using OpenMDAO (Open-source Mu...
