A Simulation Test Bench for Decay Times in Room Acoustics

R. Magalotti [1], V. Cardinali [1],
[1] B&C Speakers S.p.A., Bagno a Ripoli (FI), Italy

An important yet rarely explored problem in room acoustics is how to correlate the decay times of modal resonances to the acoustic properties of the boundaries (walls). The room response is often described by reverberation times, but the reverberation model breaks down at low frequency, ... Saiba Mais

Simulation of Lattice Structures in Orthopedic Corsets

W. Rieder [1],
[1] Switzerland Innovation Park Biel-Bienne, Switzerland

Digitization is affecting more and more industrial sectors. In the field of orthopedic technology, new technologies such as 3D scan and 3D printing are used in production. This opens up new fields of application for the simulation. The example of a scoliosis corset shows how the new ... Saiba Mais

When Precise Numerical Predictions Come to the Rescue of Liquid Lubrication

J.-D. Wheeler [1], V. Bruyere [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Whereas some bearings designed in the 19th century are still working properly nowadays, some others which were recently designed encountered premature failures. Tribological applications, such as journal bearings or rolling element bearings, are generally ruled by complicated ... Saiba Mais

Simulation of an Ethane Steam Cracking Reactor for Ethane-Propane Mixtures

R. Martinez [1], J. A. Galán [2], Y. Amaya [1], H. S. Arenas [1]
[1] Universidad Industrial de Santander, Bucaramanga, Santander, Colombia
[2] Empresa Colombiana de Petróleos, Barrancabermeja, Santander, Colombia

This study allows to establish the possibility to carry out the pyrolysis of mixtures of ethane-propane in an existing steam-cracking reactor (SCR) originally designed for ethane pyrolysis. The final goal of this study was to minimize new investments, e.g. a purchase of new equipment, ... Saiba Mais

Multidisciplinary Simulation Based Learning Enhancement Module

A. K. Datta [1], M. Ukidwe [1], A. Warning [1], K. Bhunia [1],
[1] Cornell University, Ithaca, NY, USA

Simulation based learning modules can be effectively introduced to a large audience with customization. The simulation modules can essentially engage learners from diverse background and efficiently introduce the quantitative approaches to non-engineers. Moreover, those can greatly help ... Saiba Mais

Dependence of Potential and Ion Distribution on Electrokinetic Radius in Infinite and Finite-length Nano-channels

J. Schiffbauer[1], J. Fernandez[2], W. Booth[1], K. Kelly[3], A. Timperman[3], and B. Edwards[1]
[1]Physics Dept. West Virginia University, Morgantown, WV, USA
[2]Chemical Engineering Dept,West Virginia University, Morgantown, WV, USA
[3]Dept. of Chemistry, West Virginia University, Morgantown, WV, USA

A site-binding/dissociation model is used to determine surface charge in numerical studies of the equilibrium potential and ion distributions inside infinite and finite-length nano-channels. This COMSOL model allows us to investigate the response of surface (zeta) potential to ... Saiba Mais

Validation of DNS Techniques for Dynamic Combined Indoor Air and Constructions Simulations Using an Experimental Scale Model

T. van Goch, and A. van Schijndel
Eindhoven University of Technology, Eindhoven, Netherlands

This paper presents a study on the application of Direct Numerical Solving (DNS) techniques using an experimental scale model. COMSOL Multiphysics is promising in solving dynamic heat and air transport. The experiments can be extremely useful as benchmark for CFD codes. Saiba Mais

In-Situ Detection of Inclusions in Liquid Steel

X. Wang, R. Guthrie, and M. Isac
McGill Metals Processing Centre, Montreal, Canada.

A numerical multiphase flow model is proposed to predict the behavior and motion of entrained inclusions in liquid steel, as they enter the orifice of a LiMCA (Liquid Metal Cleanliness Analyzer) sensor for assuring steel quality. The method of measurement is based on the electric sensing ... Saiba Mais

Analyzing a Malfunctioning Clarifier with COMSOL’s Mixture Model

A. de Niet, A. van Nieuwenhuijzen, and A. Geilvoet
Witteveen+Bos, Deventer, The Netherlands

Clarifiers are used to separate sludge and water in waste water treatment plants. In this paper we analyze a malfunctioning clarifier using the mixture model. We are able to receive model results that are reasonably close to measurements from the real clarifier. With the model we can ... Saiba Mais

Investigation of Natural Convective Air Flow Field through Comb Channels

R. Umhack, M. Rainer, M. Tamerle, and G. Hillmer
Process-, Environmental- and Bio- technology, MCI - University of Applied Sciences, Innsbruck, Austria

A new type of radiator with a package of combs, to gain a larger area for heat exchange, instead of trapezoidal convector plates, is investigated. The main aim is to find the optimal comb diameter. To solve this problem, CFD (computational fluid dynamics) with COMSOL Multiphysics is ... Saiba Mais
