Comparison of Experimental Measurements with COMSOL Multiphysics® CFD Simulations of Erosional Growth of a Soil Pipe

J. Nieber[1], G. Wilson[2], G. Fox[3]
[1]University of Minnesota, USA
[2]USDA-ARS, USA
[3]North Carolina State University, USA

Soil pipes are large contiguous macropores that exist in soils or geological materials. These macropore features generally serve as conduits for rapid movement of water through soils or geological material, and are generally oriented nearly parallel to the land surface. Soil pipes are ... Mehr lesen

Impact of Operating Parameters on Precursor Separation in "Air Hockey" Spatial Atomic Layer Deposition Reactor

J. Grasso[1], B. Willis[1]
[1]University of Connecticut, USA

A defining characteristic of atomic layer deposition (ALD) is the sequential exposure of a surface to self-limiting, saturating reactions. Temporal ALD operates through intermittent purge cycles, while spatial ALD relies on physical separation accomplished by delivering reactants through ... Mehr lesen

Adiabatic Calorimetry of a Thermal Runaway Reaction

C. Ivory[1], M. Levin[1]
[1]Washington State University, USA

Modern adiabatic calorimeters are designed to keep thermal inertia as low as possible so that temperature-dependent reaction rates and heats of reaction can be accurately extracted from the thermocouple data. Published models of this type of equipment are generally zero dimensional (0D) ... Mehr lesen

A COMSOL Multiphysics® Finite Element Model of the Diffusion Profile of Brain Derived Neurotrophic Factor: Biological Validation through a Microfluidics Device

S. Bharadwaj[1], A. Matsuoka[1], A. Oleksijew[1], H. Chang[1], C. Miller[1], R. Heuer[1], K. Nella[1], C. Richter[1], J. Kessler[1]
[1]Northwestern University Feinberg School of Medicine, USA

Background: Sensorineural hearing loss is the most common type of hearing impairment. One novel method to treat this form of hearing loss is by regenerating the synaptic connections between the extant Spiral Ganglion Neurons (SGNs) and transplanted human stem cell derived SGNs. Brain ... Mehr lesen

Hydromechanical Modelling of Gas Migration in Host Rocks for Nuclear Waste Repositories

J. Yang[1], M. Fall[1]
[1]University of Ottawa, Canada

Deep geological repositories (DGRs) are currently being proposed in several countries to deal with the nuclear waste. The safe long-term disposal of the waste is guaranteed by a multi-barrier system, which includes a natural barrier (host rocks) and an engineered barrier system. Large ... Mehr lesen

Experimental and Numerical Evaluation of Metal Foam Thermal Performance Interacting with Nanofluid: Applications in Electronics Cooling

C. Welsford[1], C. Delisle[1], Z. Saghir[1]
[1]Ryerson University, Canada

The present study aimed to determine the effect of nanofluid concentration, channel inclusion, flow rate, and heat flux, on the thermal effectiveness of Al2O3 nanofluid and 6061-T6 aluminum foam metal with 91% porosity and 40 linear pores per inch as components in a heat exchange system ...

Phase Field Modelling of Gas Migration in Bentonite-Based Barrier Material

G. Guo[1], M. Fall[1]
[1]University of Ottawa, Canada

Bentonite based materials (BBM) are considered as ideal buffer materials for deep geological repository (DGR) for nuclear wastes because of several desirable properties, such as low permeability, high adsorption capacity and proper swelling ability (Guo and Fall 2018). However, gas ... Mehr lesen

[1] 清华大学汽车安全与节能国家重点实验室,北京,中国

为了提高质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell, PEMFC)的效率、延长其寿命,水管理是必须解决的问题。由于原位观测电堆内部水传递状态难度较大,研究PEMFC机理并进行建模,以此预测电堆内部水传递状态具有重要意义。 本研究利用COMSOL Multiphysics®建立了沿质子传递方向的PEMFC一维动态机理模型。模型采用多孔介质中的多相混合物传递理论描述两相流,并对催化剂层的Schroeder’s paradox进行了数学描述。模型将PEMFC划分为阳极GDL、质子交换膜和阴极GDL三个域 ... Mehr lesen
