We investigate the stability of thin viscous films coated on the inside of a horizontal cylindrical substrate. In such a case, gravity acts both as a stabilizing force through the progressive drainage of the film and as a destabilizing force prone to form ...
Energy pile foundation can expel and extract heat into and from the ground in summer and winter, respectively. The discharge and extraction of heat induce cyclic thermal load in piles and may lead to serviceability problems. So far, the effects of cyclic h ...
The operation of energy pile in summer can expel excessive heat of the buildings into the ground by the use of a heat pump. Despite of having been implemented for decades, the design of energy pile still relies heavily on empiricism as there is still limit ...
Centrifuge experiments modeling single-phase flow in prototype porous media typically use the same porous medium and permeant. Then, well-known scaling laws are used to transfer the results to the prototype. More general scaling laws that relax these restr ...

The effect of drainage front morphology on gaseous diffusion through partially saturated porous media is analyzed using the lattice Boltzmann method (LBM). Flow regimes for immiscible displacement in porous media have been characterized as stable displacem ...
The concept of “mobile” and “immobile” fluid regions (as incorporated in the Two-Region Model, TRM) is often used in the governing equation to model tailing in solute breakthrough curves (BTC). In this paper, we apply the TRM and its parent equation, the A ...
Unstable flow can result in the formation of fingers during infiltration into dry soil. Centrifuge modeling is a potentially useful tool to study the relationship between finger size, spacing, and velocity. It can also be used to investigate solute transpo ...
The scaled modelling of non-aqueous phase liquid (NAPL) transport in porous media is examined with particular reference to the use of a geotechnical centrifuge as a tool for modelling this phenomenon. Scaling relationships for NAPL mobility are derived. Th ...
This technical note examines the feasibility of physically modelling unstable water flow in the form of fingers in the vadose zone. A scaling analysis is performed based on published expressions for the width and velocity of fingers, as well as the distanc ...
Over the past decade, research workers have started to investigate problems of subsurface contaminant transport through physical modelling on a geotechnical centrifuge. A major advantage of this apparatus is its ability to model complex natural systems in ...
