Least – Squares Method For Estimating Diffusion Coefficient
Abstract: Determination of the diffusion coefficient on the base of solution of a linear inverse problem of the parameter estimation using the Least-square method is presented in this research. For this propose a set of temperature measurements at a single sensor location inside the heat conducting body was considered. The corresponding direct problem was then solved by the application of the ...
متن کاملLEAST – SQUARES METHOD FOR ESTIMATING DIFFUSION COEFFICIENT
Determining the diffusion coefficient based on the solution of the linear inverse problem of the parameter estimation by using the Least-square method is presented. A set of temperature measurements at a single sensor location inside the heat conducting body is required. The corresponding direct problem will be solved by an application of the heat fundamental solution.
متن کاملAn atmospheric electrical method to determine the eddy diffusion coefficient
The ion–aerosol balance equations are solved to get the profiles of atmospheric electric parameters over the ground surface in an aerosol-rich environment under the conditions of surface radioactivity. Combining the earlier results for low aerosol concentrations and the present results for high aerosol concentrations, a relation is obtained between the average value of atmospheric electric spac...
متن کاملA modified diffusion coefficient technique for the convection diffusion equation
A new modified diffusi on coefficient (MDC) technique for solv ing conve ction diffusion equation is proposed. The Galerkin finite-element discretization process is applied on the modified equation rather than the original one. For a class of one-dimensional convec-tion–diffusion equations, we derive the modi fied diffusion coefficient analytically as a function of the equation coefficients and...
متن کاملTracer dispersion study: Diffusion coefficient and modeling results
This work compared the outcome of tracer dispersion experiments with the results of a far field numerical modeling. The studies were carried out on two different locations from Rio de Janeiro coast: the first near the city of Maricá, approximately 30 km east from the Guanabara Bay, and the second inside the bay, at São Gonçalo. For the tracer experiment, it was used a Rhodamine, Amidorhodamine ...
