Following the launch of the Government Construction Strategy in 2011, the UK construction sector has witnessed a significant increase in the awareness and adoption of Building Information Modelling (BIM). As recognised by the strategy, there are synergies between Lean Construction and BIM. BIM implementation demands changes in existing process and procedures for design and construction, represe...

micro scale gas flows has attracted significant research interest in the last two decades. in this research, the fluid flow of gases in the stepped micro-channel at a wide range of knudsen number has been analyzed with using the lattice boltzmann (mrt) method. in the model, a modified second-order slip boundary condition and a bosanquet-type effective viscosity are used to consider the velocity...

We simulate flow and transport directly on pore-space images obtained from a microcomputed-tomography (micro-CT) scan of rock cores. An efficient Stokes solver is used to simulate lowReynolds-number flows. The flow simulator uses a finite-difference method along with a standard predictor/corrector procedure to decouple pressure and velocity. An algebraic multigrid technique solves the linear sy...

abstract weirs are the most common structures for discharge measurement in engineering research. streamline curvature, non hydrostatic pressure distribution on weir and nappe adherence to the weir lead to differences between calculated and measured discharges. thus discharge coefficient, which is the ratio of real and theoretic discharges, is usually less than unity. in circular weirs the press...

In this paper, we discuss some novel techniques for modeling sedimentation and compaction using fully unstructured meshes. The numerical modeling of the sedimentation process is a critical part of basin simulation and synthetic stratigraphy modeling. Normally, structured curvilinear meshes are used to represent sedimentary sequences to be deposited during the simulation. Using this approach, 2D...
