Abstract:The surface characteristics, such as wettability and roughness, play an important role in heat transfer performance in the field of microfluidic flow. In this paper, the process of a hot liquid flowing through a microchannel with cold walls, which possesses different surface wettabilities and microstructures, is simulated by a transient double-distribution function (DDF) two-phase thermal lattice Boltzmann BGK (LBGK) model. The Shan-Chen multiphase LBGK model is used to describe the flow field and the independent distribution function is introduced to solve the temperature field. The simulation results show that the roughness of the channel wall improves the heat transfer, no matter what the surface wettability is. These simulations reveal that the heat exchange characteristics are directly related to the flow behavior. For the smooth-superhydrophobic-surface flow, a gas film forms that acts as an insulating layer since the thermal conductivity of the gas is relatively small in comparison to that of a liquid. In case of the rough-superhydrophobic-surface flow, the vortex motion of the gas within the grooves significantly enhances the heat exchange between the fluid and wall.

“…Percolation algorithms and operational research network analysis have been used to derive pore space flow properties (Matthew et al 1995). New models that use multi-phase latticeBoltzmann methods (LBM) to simulate virtual intrusion in PS are under development (Hyväluoma et al 2004). However, LBM have slow convergence and thus require powerful computational facilities (i.e., parallel computing) and large memory availability to keep track of the 16 or 19 components of the density distribution at each wetted-site (i.e., voxel) in which the 3D PS is discretized (see D3Q19 LB-BGK models).…”

Morphological measurements in 3D for pore space characterization (connectivity, pore-body/throat classification, shape factors, virtual fluid intrusion) are based on computed intensive digital-thinning operations for skeletonization and medial axis extraction from 3D digital images. We present an alternative method that is measurably faster and allows sub-voxel definition of the pore space network. The method allows extracting-based on morphological considerations only-the centered and shortest stream-lines-i.e., the paths-to follow in order to go through the pore space from one given point to another and to exit. In addition the method penalizes long and narrow pore-throats in favor of short stubby/ones-i.e., it has a built-in exemplification capacity. It exploits well-established mathematical methods successfully applied in medical endoscopy.Keywords Porous media · Pore space · Skeleton · Fluid intrusion · Permeability MotivationModern 3D imaging systems allow the reconstruction of representative equivalent volumes (REV) of porous media with resolutions suitable for morphological characterization of the pore space (PS) structure. Most of these geometrical and morphological measurements are deduced from the so-called medial axis (MA). In addition, the pore space MA is the basis for network modeling that is one of the most commonly used methods for predicting mono-and multi-phase fluid displacement phenomena.Thinning is the process of reducing the shape of a digital object to a simpler version that still retains the essential features of the original. The thinned version of the shape is called the skeleton. When the skeleton is centered with respect to the boundaries of the original object, it is referred to as the MA or medial-surface. These are two
