Modelling of a Thermal Time-of-Flight Sensor for Low Rate Open Channel Flow

C. Panhans[1], T. Koch[2], S. Leonhard[1], R. Hilliges[1], R. Stolle[1], A. Frey[1]
[1]University of Applied Sciences Augsburg, Germany
[2]Comsol Multiphysics GmbH, Germany

Water transport in the public sewer system is often based on open channel flow, e.g. in a DN100 drainage pipe. Especially for low flow rates of less than 10 mL/s and with water levels of less than 4 mm, flow sensors are hardly available. In order to enable the measuring of very low ... Read More

Pumping Tests: Comparison of 2D Numerical and 1D Analytical Solutions

E. Holzbecher[1]
[1]German University of Technology in Oman, Oman

For hydrogeologists pumping tests are the most common method to obtain characteristic aquifer properties, like transmissivity and storativity. For the evaluation of pumping tests it is common practice to compare field measurements and 1D analytical solutions. Numerical methods offer the ... Read More

Modelling the Structural-Dynamics of Electrical Overhead Line Power Conductors

M. Al Aqil[1], K. Kopsidas[1]
[1]The University of Manchester, United Kingdom

As a general definition, the presence of any repeated motion after a regular interval of time is known as vibrations. The basic theory of vibrations is described by the system of forces acting on a moveable and deformable body. The natural phenomena existing in the universe such as ... Read More

Numerical Simulation of Residence Time Distributions of Coiled Tubular Reactors

S. Eller[1], M. Fassbender[1], G. Luinstra[1]
[1]University of Hamburg, Germany

The fabrication of new reactor types has been simplified significantly by the rapid progression within the field of additive manufacturing. A reactor can be fit to nearly every specific task by varying its geometry and therefore its reactant hold-up and flow conditions in continuous ... Read More

Method to Reduce Calculation Time in Multiphysics Modelling of Welding Processes. Application to Laser and GMAW Welding

M. Courtois[1], M. Carin[1], P. Le Masson[1], S. Cadiou[1], S. Gaied[2]
[1]IRDL - Univ Bretagne Sud, France
[2]ArcelorMittal, France

The heat and fluid flow calculation inside the melt pool in welding processes is a complex challenge. It can be useful to predict defects in the weld seam or to study the influence of some process parameters. Even if the required equations are mastered over the last few years, the cost ... Read More

Introducing Novel Convergent Geometries to Enhance Pipe Flow Convective Heat Transfer

A. Al-Sammarraie[1], K. Vafai[1]
[1]University of California, Riverside, USA

A wide variety of engineering applications, such as electronics, solar collectors, and internal combustion engines produce heat. This heat can be a positive or negative aspect for a particular application. Enhancing heat transfer has encouraged many researchers to investigate various ... Read More

Mixing Considerations in Chemical Reactor Scale-Up

A. Fiore[1], A. Spann[1]
[1]Veryst, USA

The yield and selectivity of a chemical reactor are controlled by the rates of desired reactions relative to those of undesired side reactions. These reaction rates are controlled by the local concentration of reactants, as often described by elementary rate laws. Chemical engineers ... Read More

Finite Element Modelling and Simulation Tools for Investigation of the Process and Materials 3D-Printed by Selective Laser Melting

H. Jean Willy[1], X. Li[1], J. Ding[1]
[1]National University of Singapore, Singapore, Singapore

Selective Laser Melting (SLM), like many other additive manufacturing techniques, offers flexibility in design expected to become a disruption to the manufacturing industry. The current cost of SLM process does not favor a try-and-error way of research; which gives more room for ... Read More

Analysis of Micromixers to Minimize Scaling Effects on Reverse Osmosis Membranes

J. Walker[1]
[1]U.S. Army, USA

Abstract The standard diamond-shaped mesh spacers commonly used in spiral wound membrane elements results in non-ideal hydrodynamics that can lead to fouling, which ultimately reduces the flux of water through the membrane and the operational life of the unit. To address this ... Read More

Three-Dimensional Mixed Convection in a Rectangular Duct

A. Oluwade[1], T. Onyenze[1], E. Glakpe[1]
[1]Howard University, USA

Numerical study of fluid flow and heat transfer in a finite three-dimensional rectangular, horizontal duct of length to width, and length to height ratio of 12:1 is investigated in this study. The left wall of the duct is uniformly heated while the right, top, and bottom walls are ... Read More
