complex heat transfer phenomena (including unsteady state conduction, convection and solidification processes) occur in steel belt conveyer sulfur granulating method. numerical simulation of this technique is performed via a comprehensive and multifaceted one dimensional model. since the air situated between the adjacent sulfur pastilles is essentially stagnant, therefore, the surface temperatu...

We present a three-dimensional modeling study of gas flow in the unsaturated fractured rock of Yucca Mountain. Our objective was to estimate large-scale fracture permeability, using the changes in subsurface pneumatic pressure in response to barometric pressure changes at the land surface. We incorporate the field-measured pneumatic data into a multiphase flow model for describing the coupled p...

The construction industry is primarily concerned with increasing project quality while simultaneously maintaining and increasing the efficiency with which that quality is attained. It is proposed that both of these objectives can be achieved using a combination of existing visual analysis and three-dimensional modeling tools to identify, in real time, inconsistencies between design plans and ph...
