Ammonia Removal From Water by a Liquid-Liquid Membrane Contactor Under a Closed Loop Regime

E. Licon[1], S. Casas[1], A. Alcaraz[1], J.L. Cortina[1], C. Valderrama[1]
[1]Universitat Politécnica de Catalunya, Barcelona, Spain

Ammonia separation from water by membrane contactor was simulated on transient state and compared with experimental data. Aqueous low concentrated solution of ammonium with high pH has been pumped inside the hydrophobic hollow fibers, acid solution in the outside part. The system is in ... Read More

CFD Analysis of a Printed Circuit Heat Exchanger

K. Wegman [1], X. Sun [1],
[1] Department of Mechanical and Aerospace Engineering, Ohio State University, Columbus, OH, USA

In this experiment, the performance of a Printed Circuit Heat Exchanger (PCHE) was studied using COMSOL Multiphysics® software. PCHEs are diffusion bonded heat exchangers containing semicircular, chemically etched flow paths. Helium was used as the working fluid on both the hot and cold ... Read More

Non-isothermal Flow of CO2 in Injection Wells: Evaluation of Different Injection Modes

O. Silva [1],
[1] Amphos 21 Consulting S.L., Barcelona, Spain

Injection conditions of CO2 at the wellhead may play a major role on the flow behavior through the wellbore. The density and the injection rate reached at the bottomhole are key factors affecting the performance and efficiency of CO2 geological storage. In this work, a model of non ... Read More

K. Cluff[1], L. Saeednia[2], H. Mehraein [1], R. Asmatulu[2]
[1]Department of Bioengineering, Wichita State University, Wichita, KS, USA
[2]Department of Mechanical Engineering, Wichita State University, Wichita, KS, USA

Polymeric hydrogel is a promising class of drug delivery systems with the controlled release behavior in the body. In-situ forming hydrogels can be injected into the body as a fluid which forms a gel within the body tissue and improve the efficacy of the drugs. Various polymers have been ... Read More

Modeling of Residual Stresses in a Butt-welded Joint with Experimental Validation

V. Srivastava [1],
[1] Naval Materials Research Laboratory (NMRL), Defence Research and Development Organization (DRDO), Ambernath, Thane, Maharashtra, India

2D-modeling of arc welding in butt-joint configuration was performed in this study considering thermal-structural interactions. Thermal behavior was modeled in COMSOL Multiphysics® using the Heat Transfer Module with weld heat input as a Gaussian pulse whereas structural behavior using ... Read More

A Wall-Cooled Fixed-Bed Reactor Model for Gas-Phase Fischer-Tropsch Synthesis

A. Nanduri [1], P. L. Mills [1],
[1] Department of Chemical and Natural Gas Engineering, Texas A&M University - Kingsville, Kingsville, TX, USA

In the early 1920’s, Gas-To-Liquids (GTL) and Coal-To-Liquids (CTL) technologies were developed to account for the depleting crude oil resources [1]. During this period, Franz Fischer and Hans Tropsch developed a process to convert synthesis gas (syn gas), derived from coal ... Read More
