An Application for Predicting Environmental Conditions within an Additive Manufacturing Facility

A. Roberts[1], P. Ioannou[1]
[1]The Manufacturing Technology Centre (MTC), United Kingdom

Environmental factors such as temperature and humidity can significantly affect the quality of the metal powder used in power bed fusion additive manufacturing, leading to variations in the integrity of finished components. It is therefore important to monitor and minimize the exposure ... 詳細を見る

Coupling Non-Newtonian Fluid Flow and Heat Transfer Inside a Scraped Surface Heat Exchanger

A. Plana-Fattori[1], D. Flick[1]
[1]UMR 1145 Ingénierie Procédés Aliments, INRA, AgroParisTech, Université Paris-Saclay, France

Scraped-surface heat exchangers (SSHEs) handle products that are viscous, that contain particles, and that tend to deposit on the heat transfer surface. The rotating scraper blades continuously remove any deposition on the heating or cooling surface, thereby maintaining the efficiency of ... 詳細を見る

Photovoltaic Module Design and Mounting for Operation at Elevated Ambient Temperatures

A. García Zubiría[1], A. Fragaki[1], I. Khan[1]
[1]University of Central Lancashire, United Kingdom

Irradiance is fundamental in the energy production of photovoltaic (PV) modules and models can be developed using just irradiance data. However, module temperature has also significant impact on the power output. In locations with high ambient temperatures PV module performance can be ... 詳細を見る

Laser Assisted Bonding (LADB) Thermal Modeling with COMSOL Multiphysics®

G. Spinola Durante[1], R. Jose James[1], E. Rutz-Innerhofer[1], K. KRASNOPOLSKI[1]
[1]CSEM SA, Switzerland

New emerging trends in the MEMS market are linked to the availability of small, reliable and miniature sensors for harsh environment applications to increase penetration in all application fields, considering very wide operating condition ranges. These trends are pushed forward by the ... 詳細を見る

Fluid-Structure Interaction of Coupled Valves in Sucker Rod Pump

S. Jalikop[1], B. Scheichl[2], S. Eder[1]
[1]AC2T research GmbH, Austria
[2]Technische Universität Wien, Austria

Motivation We simulate the fluid driven interaction between two dynamically coupled valves designed to work in conjunction with each other. Such interacting valves are extensively used in sucker rod pumps for oil extraction. These pumps essentially consist of a pair of ball check valves ... 詳細を見る

Numerical Investigation of Micro Droplet Contact Angle Hysteresis on a Heterogeneous Solid Surface: Application to Carbonate

M. Zaidani[1], M. Sassi[1]
[1]Khalifa University of Science and Technology, United Arab Emirates

Contact angle hysteresis is an important physical phenomenon, it is an essential parameter in wetting and capillarity, and it plays an important role in many industrial processes, especially in Enhanced Oil recovery (EOR). In this paper, the contact angle hysteresis (CAH) of ... 詳細を見る

Simulation of Bi-Material Nano-Second Laser Ablation

M. Dal[1], L. Carvalho[2], W. Pacquentin[2], a. semerok[2], H. Maskrot[2]
[1]ENSAM, France
[2]CEA, France

In the field of laser applications, surface treatment is highly studied. Two process categories are commonly used. First processes use very short pulses (femto or pico seconds) known to avoid thermal effects and to have high spatial resolutions. Second processes have higher interaction ... 詳細を見る

Geophysical Fluid Dynamics: Modelling Non-Linearly Viscous Ice-Flow to Obtain Dates of Flow Change

R. Hindmarsh[1]
[1]British Antarctic Survey and Durham University, United Kingdom

Ice flows because at low stresses it deforms viscously; the viscosity depends upon the stress. The lubrication approximation (LA) states shear stress is proportional to the product of the ice depth and surface slope. At ice divides the slope and shear stress are zero meaning the ... 詳細を見る

High-Resolution CFD Modeling of a Large-Scale Short-Term Thermal Energy Storage Unit

B. Krüger[1], F. Dammel[1], P. Stephan[1]
[1]Technische Universität Darmstadt, Germany

Small-scale short-term thermal energy storage (TES) systems and large-scale seasonal TES systems have been the focus of many research projects. However, large-scale short-term TES units have not been covered in great depth, even though they play an important role by decoupling the heat ... 詳細を見る

Predicting the Fate of Contaminant and Remediating Nano-Particles in a Polluted Aquifer with an Integrated Modeling Approach

S. Nilabh[1], F. Grandia[1]
[1]Amphos 21 Consulting S.L., Spain

The presence of anthropogenic or natural pollutants in groundwater system poses a threat to water resources. Several remediation techniques have been explored and developed to decrease the concentration of contaminants. One such remediation technique, injection of nano-particles in the ... 詳細を見る
