Hybrid or mono nanofluids for convective heat transfer applications. A critical review of experimental research [PDF]
, 2021 Research on nanofluids has increased markedly in the last two decades. Initial attention has focused on conventional or mono nanofluids, dispersions of one type of solid nano-sized particles in a base fluid.

Sub-Millimeter-Scale Measurement of Local Convective Heat Transfer Coefficient Exceeding 100 W/(m^2-K) Using an Optical Pump-Probe Method [PDF]
Measurement, 249 (2025) 117001Conventional methods for measuring the local convective heat transfer coefficient (h_c) often rely on simplifying assumptions that can compromise accuracy. Pump-probe methods like time-domain thermoreflectance (TDTR) avoid these assumptions but are limited to h_c values larger than 30 kW/(m^2-K) due to modulation frequency constraints.

Driving convection by a temperature gradient or a heat current [PDF]
, 2006 Bifurcation properties, stability behavior, dynamics, and the heat transfer of convection structures in a horizontal fluid layer that is driven away from thermal equilibrium by imposing a vertical temperature difference are compared with those resulting from imposing a heat current.

HEAT TRANSFER ENHANCEMENT IN LAMINAR CONVECTIVE HEAT TRANSFER WITH NANOFLUIDS
Proceeding of TMNN-2011. Proceedings of the International Symposium on Thermal and Materials Nanoscience and Nanotechnology - 29 May - 3 June , 2011, Antalya, Turkey, 2011 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 ...
