Thermal Hydraulic Study for Heavy Liquid Metal Flows using COMSOL Multiphysics
Liquid metals are the extensively used as coolants in nuclear reactors.However, the heat transfer mechanism differs significantly in low Prandtl number heavy liquid metals (HLM’s) than those observed in common fluids. It is crucial to have the accurate heat transfer correlation for the ... Read More
Flow of Dry Foam in a Pipe
Due to the coupling of foam flow with foam generation step, the earlier studies on foam flow have not led to consistent results. An increase in flow rate to obtain ?P vs. Q data changes the foam under investigation itself. The controlled experiments carried out earlier in our group ... Read More
Miscible Viscous Fingering: Application in Chromatographic Columns and Aquifers
When a less viscous fluid displaces a more viscous one in a porous medium or Hele-Shaw cell, the interface between the two miscible fluids does not remain flat and deforms into fingers growing in time [1]. It occurs due to the faster movement of less viscous fluid than the more viscous ... Read More
Numerical Study of Navier-Stokes Equations in Supersonic Flow over a Double Wedge Airfoil using Adaptive Grids
Numerical study of aerodynamic characteristics in steady laminar supersonic flow over a double wedge airfoil is carried out using commercially available finite element based CFD tool COMSOL Multiphysics. The aerodynamic characteristics of double wedge airfoil like lift and drag are ... Read More
Flare System Pressure Drop Calculations Using COMSOL
COMSOL Multiphysics has been used to validate and check the design of a header transporting ammonia gases released from pressure safety valves (PSVs) to the tip of the flare. The header is part of a dedicated flaring system to contain emissions from ammonia storage tanks. The two main ... Read More
Design of a Controlled Dosing Scheme for Liquids using a Venturi
Dosing a predetermined quantity of one liquid into another, in a controlled fashion, is a process often encountered in a variety of operations at both industrial and laboratory scales. This process becomes a challenging one if it has to be carried out in a continuous mode, without using ... Read More
Dynamics of a Sessile Droplet Evaporation
Evaporation of sessile droplets is associated with simple phenomena such as the ring-like spot left by a drying coffee droplet. Evaporation rate plays an important role on the convective motion inside the droplet. These fluxes are for example one of the factors responsible for amyloid ... Read More
Numerical Simulation of Oil Recovery by Polymer Injection using COMSOL
In this paper we used COMSOL Multiphysics to model basic physico-chemical effects relevant in polymer enhanced oil recovery (EOR) such as non-Newtonian rheology of the displacing phase, permeability reduction, adsorption and salinity effects. COMSOL\'s PDE interface as well as Species ... Read More
Modeling of HTPEM Fuel Cell Start-Up Process by Using COMSOL Multiphysics
HTPEM fuel cells are considered to be the next generation fuel cells. The electrochemical kinetics for electrode reactions are enhanced by using PBI membrane at an operation temperature between 160-180 °C comparing to LTPEM fuel cells. But starting HTPEM fuel cells from room temperature ... Read More
Ventilation System of a Microwave Assisted Drying Kiln
The paper presents the analysis and optimization of the ventilation system inside of a drying lumber kiln. As with any part of the manufacturing process, improper drying techniques cause quality degradation and considerable amount of energy loose. The improvement and optimization of ... Read More
