Pseudo-spectral Matrix and Normalized Grunwald Approximation for Numerical Solution of Time Fractional Fokker-Planck Equation
This paper presents a new numerical method to solve time fractional Fokker-Planck equation. The space dimension is discretized to the Gauss-Lobatto points, then we apply pseudo-spectral successive integration matrix for this dimension. This approach shows that with less number of points, we can approximate the solution with more accuracy. The numerical results of the examples are displayed.
متن کاملStudy of Low-Temperature-Combustion Diesel Engines
Fuel cells have been recognized as a feasible alternative to current IC engines. A significant technical problem yet to be resolved is the on bound fuel supply before fuel cells can be practically used for vehicles. Use of an on-board fuel reformer can mitigate the fuel supply issue. In particular, using a diesel engine as on-board fuel reformer, combined with a fuel cell, is a strong candidate...
متن کاملEquivalent Oxidation Exposure - Time for Low Temperature Spontaneous Combustion of Coal
Coal is a combustible material applicable to a variety of oxidation scenarios with conditions ranging from atmospheric temperature to ignition temperature. One of the most frequent and serious causes of coal fires is self-heating or spontaneous combustion. Opening an underground coal seam to mine ventilation air, such as long-wall gob and goaf areas and coal stockpiles, creates a risk of sponta...
متن کاملTime-Asymptotic Limit of Solutions of a Combustion Problem
A combustion model which captures the interactions among nonlinear convection, chemical reaction and radiative heat transfer is studied. New phenomena are found with radiative heat transfer present. In particular, there is a weak detonation solution for each radiative heat loss coeecient. The speed of the weak detonation wave decreases as the heat loss coeecient increases and the detonation wav...
متن کاملLow-temperature CO oxidation over Cu/Pt co-doped ZrO2 nanoparticles synthesized by solution combustion
Zirconia (ZrO2) nanoparticles co-doped with Cu and Pt were applied as catalysts for carbon monoxide (CO) oxidation. These materials were prepared through solution combustion in order to obtain highly active and stable catalytic nanomaterials. This method allows Pt2+ and Cu2+ ions to dissolve into the ZrO2 lattice and thus creates oxygen vacancies due to lattice distortion and charge imbalance. ...
