Abstract

An investigation of the basic nanoconvective flow to be applied in evaluating the limit of validity of the transient hot wire experimental (THW) method for nanofluids is presented. Analytical solutions for the basic temperature, basic nanoparticles volume fraction, and basic natural convection velocity are being derived and analyzed. These basic solutions are needed in follow-up linear and nonlinear stability analyses aiming to establish the time required for natural convective heat flux to develop and invalidate transient hot wire experimental results. While the first part of the paper presents the current status of knowledge related to the transient hot wire experimental method and the theoretical aspects governing the validity of the method, the second part aims at presenting new results that can provide additional and more accurate conditions for the validity of that experimental method.
