A finite difference method for fractional diffusion equations with Neumann boundary conditions

open access: yesOpen Mathematics, 2015
A finite difference numerical method is investigated for fractional order diffusion problems in one space dimension. The basis of the mathematical model and the numerical approximation is an appropriate extension of the initial values, which incorporates

Comparative Study of Experimental Methods for Measuring Thermal Properties of 100Cr6 Steel Powders

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the thermal properties of 100Cr6 steel in both bulk and powder forms. Measuring the very low thermal conductivity typically exhibited by powders poses significant challenges. To address this, two novel measurement techniques—temperature gradient and finite laser pulse response—are introduced and evaluated by comparison with the ...
