Mung bean is a good source of protein, vitamins, certain minerals and antioxidant compounds for the vegetarian population of the country. During storage, high moisture content of mung bean leads to the maximum quality and quantity losses due to the growth of fungus and insects. Thus drying of mung bean grains is an important postharvest operation to increase the shelf life of mung bean. Infrared ...

Numerical Analysis of Heat Generation in Ball End Magnetorheological Finishing

[1] CSIR - Central Scientific Instruments Organisation, Chandigarh, India

In the Ball End Magneto rheological Finishing, due to heat generation by thermal agitation the effect of MRF finishing reduces and this ultimately hampers the process of the precision finishing and density of MR fluid too, which therefore results in instability of MR fluid.

Numerical Analysis Of Entry Length In Cleaning Test Rig

N. Nordin [1]
[1] Universiti Putra Malaysia, Malaysia

Fouling and cleaning processes present a major impact to the manufacturing industry in terms of economics, product quality, product safety, and plant efficiency. An efficient cleaning process is essential is order to remove fouling to maintain quality and safety of production process as well as the product. Thus, cleaning should be done with minimum cost and time, and understanding soil ...

Multiphysics Simulation of Ion Concentration Polarization Induced by Nanoporous Membranes in Dual Channel Devices

[1] Ulsan National Institute of Science and Technology, Ulsan, Korea

ICP phenomenon has been widely used for fabricating microfluidic devices of pre-concentration, micromixing and desalination. However, theoretical research and simulation of ICP have not been carefully dealt with. We provide a multiphysics simulation of a DC-ICP device based on improved numerical settings in this work.

[1] Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu, India

Prototype Fast Breeder Reactor (PFBR) has two independent, diverse, fast acting & fail safe shut down systems to achieve the required level of safety & reliability (1). The shut down systems comprises of nine numbers of Control & Safety Rod Drive Mechanisms (CSRDM) & three numbers of Diverse Safety Rod Drive Mechanisms (DSRDM). DSRDM facilitates SCRAM of the reactor on abnormal ...

A Semplified Model for the Evolution of a Geothermal Field

L. Meacci[1], A. Farina[1], F. Rosso[1], I. Borsi[1], M. Ceseri[1], and A. Speranza[1]


[1]Dipartimento di Matematica U. Dini, Università degli Studi di Firenze, Firenze, Italy

The problem is to understand how a geothermal field can evolve from a water dominated state into a vapor dominated one. A first answer to this question is given by a simplified mathematical model of the dynamics of a geothermal field in which the geothermal fluid is entirely composed by pure H2O. We considered a 1-D geometry and we developed a dynamic model that presents a clear interface ...

An Extension of Lauwerier’s Solution for Heat Flow in Saturated Porous Media

[2]Deltares and TU-Delft, Delft, The Netherlands

One of the crucial topics in this century is sustainable energy. In this respect, the exploitation of geothermal energy from deep hot aquifers becomes opportune. Hence, insight is required in the heat balance of potential aquifer systems. Essential issues are convection, conduction and dispersion. This article focuses on Lauwerier’s problem. As an extension, it is suggested that beside ...

Towards a Model for Simulating Driving Rain on an Inclined Roof during Wind Gusts and Heavy Rain Intensity

A.W.M. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

The roof of a well known shopping place in Amsterdam collapsed during a storm with heavy rain showers in 2002. One of the main problems was the malfunction of the draining system. Another problem was that driving rain water apparently washed over edges that where designed to hold the water. This short paper presents the progress of using COMSOL to simulate the height of the water near the edges ...

Quench Propagation in 1-D and 2-D Models of High Current Superconductors

G. Volpini[1]
[1]LASA Lab., Milan Dept., Istituto Nazionale di Fisica Nucleare, Milano, Italy

The understanding of quench, or the sudden transition to the normal state of a high-current Superconductor (SC), is fundamental for the design of a SC magnet, and it is widely discussed in the literature. This paper presents some simple COMSOL models, which are compared with well-known approximate formulae and some experimental results. These models allow a more precise description than it is ...

Use of COMSOL as an Educational Tool Through its Application to Ground Water Pollution

A. Modaressi-Farahmand-Razavi[1]
[1]MSS-Mat Laboratory, CNRS, Ecole Centrale Paris, Ch√Ętenay Malabry, France

Ensuring the quality of underground water and controlling its quantity is of major concern for the population. Therefore, this subject attracts many students from different specialties at different levels of their curriculum. In fact, the pedagogic objectives of the course may be different according to the level or/and interest of the students and COMSOL is used due to its versatility. In this ...
