On three phase lags thermodi¤usion theory in micropolar porous circular plate

The present work examines a two dimensional axisymmetric problem of micropolar porous thermodi¤usion circular plate due to thermal and chemical potential sources. The governing equations are solved by using the potential function. The expressions of displacements, microrotation, volume 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 numerical results for resulting quantities are obtained and depicted graphically to show the in‡uence of porosity, relaxation time, phase lags, with and without energy dissipation on the resulting quantities. Some particular cases are also deduced.
