Thermal conductivity and heat transfer coefficient of concrete

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2011
A very simple model for predicting thermal conductivity based on its definiensis was presented. The thermal conductivity obtained using the model provided a good coincidence to the investigations performed by other authors. The heat transfer coefficient was determined by inverse analysis using the temperature measurements. From experimental results, it

Heat distribution in a plane with a crack with a variable coefficient of thermal conductivity

Asymptotic Analysis, 2016
We prove the existence of a solution to a problem modeling the stationary heat distribution in an inhomogeneous plane with a crack and derive explicit representations of singular terms of an asymptotic expansion of the heat flow in the vicinity of the crack tips.

APPLICATION OF SENSITIVITY COEFFICIENTS FOR HEAT CONDUCTION PROBLEMS

Numerical Heat Transfer, Part B: Fundamentals, 1999
In parameter estimation, considerable insight is provided by examining sensitivity coefficients. This article focuses on the use of sensitivity coefficients in connection with estimating thermal properties in the heat conduction equation. It is demonstrated how sensitivity coefficients are used in the design analysis of parameter estimation experiments.

Estimation of coefficient of heat conductivity and heat transfer coefficient in the numerical model of the steel quenching

2013
Temperature field is determined by specific heat capacity, c, heat conductivity coefficient, λ, density, ρ, heat transfer coefficient, α. During the developing of model steel quenching these variables must be known. Evaluation of mentioned physical properties involved in mathematical model of transient temperature field was done by the inversion method,
