Nanofluid Thermal Conductivity Prediction Model Based on Artificial Neural Network
Heat transfer fluids have inherently low thermal conductivity that greatly limits the heat exchange efficiency. While the effectiveness of extending surfaces and redesigning heat exchange equipments to increase the heat transfer rate has reached a limit, many research activities have been carried out attempting to improve the thermal transport properties of the fluids by adding more thermally c...
متن کاملThermal Model of Human Body Temperature Regulation Considering Individual Difference
This paper proposes the methodology to quantify the individual difference in temperature regulation of human body for transient simulation of body temperature. Experiments of transient thermal exposure were conducted for four subjects and the characteristics of individual difference in themoregulatory response were observed quantitatively. As the result, the differences in core temperature and ...
متن کاملPrediction of thermal conductivity of steel
A model of thermal conductivity as a function of temperature and steel composition has been produced using a neural network technique based upon a Bayesian statistics framework. The model allows the estimation of conductivity for heat transfer problems, along with the appropriate uncertainty. The performance of the model is demonstrated by making predictions of previous experimental results whi...
متن کاملVariations in the Thermal Conductivity of Insulating Thin Films with Temperature and Pressure
The thermal conductivity of a solid thin film was investigated by using two nonequilibrium molecular dynamics (NEMD) methods and changing the calculation conditions. Solid argon was selected as a target material because it has a typical Lennard-Jones (L-J) potential; hence, there was no need to consider the contribution by free electrons to a thermal conductivity. The results were not influence...
متن کاملThermal Conductivity for a Momentum Conservative Model
Abstract. We introduce a model whose thermal conductivity diverges in dimension 1 and 2, while it remains finite in dimension 3. We consider a system of oscillators perturbed by a stochastic dynamics conserving momentum and energy. We compute thermal conductivity via GreenKubo formula. In the harmonic case we compute the current-current time correlation function, that decay like t in the unpinn...
