On Three Phase Lags Thermodiffusion Theory In Micropolar Porous Circular Plate

Résumé

The present work examines a two dimensional axisymmetric problem of micropolar porous thermodiffusion circular plate due to thermal and che- mical potential sources. The governing equations are solved by using the potential function. The expressions of displacements, microrotation, vo- lume fraction field, temperature distribution, concentration and stresses are obtained in the transformed domain by using Laplace and Hankel transforms. The inversion of transforms using Fourier expansion techniques has been applied to obtain the results in the physical domain. The nume- rical results for resulting quantities are obtained and depicted graphically to show the influence of porosity, relaxation time, phase lags, with and wi- thout energy dissipation on the resulting quantities. Some particular cases are also deduced.
