Other Details

Flow and Thermal Simulation based services offered by us involves simulation of fluid flow & heat transfer using Computational Fluid Dynamics (CFD). Flow analysis also involves solving of Navier-Stokes equation by using numerical tools. Further, the flow parameters like velocity, species concentration and mass flow flux can also be obtained by solving Navier-Stokes equation. Thermal simulation involves solving of energy equations and can help in simulating distribution patterns of variables like:

Temperature

Heat loss/gain

Thermal energy

CFD for HVAC Sector:

Ventilation engineers at times need to answers to a variety of questions like "How does an air curtain responds to temperature changes like 100C?", "What are optimum positions to place the air conditioning ducts?” and other similar questions. In today’s modern sophisticated design cycles, the approach of using experience combined with intelligent engineering judgment is at times not good enough. Computational Fluid Dynamics (CFD) codes combined with now available enormous & cheap processing power can be conveniently used for conducting simulation to scientifically as well as accurately arrive at these answers.

 

Some of the other areas where our services come into use include:

 

Human Comfort Flow and Thermal Analysis:

Thermal, air-flow & relative humidity simulations help in providing the data for rooms & halls that can effectively quantify human comfort inside

These simulations can also be used to design ventilation & ducting systems that optimize human comfort with minimum power consumption

Smoke Simulation:

This involves simulation of propagation of smoke due to smoke source initiated by fire

These simulations are desirable for building engineers seeking to predict fire safety in buildings

Complex phenomenon like radiation, turbulence, buoyancy effects and others that have to be correctly simulated for obtaining good approximation of smoke movement

Air Quality Simulations:

Improvements in Indoor Air Quality (IAQ) can help in considerably improving health & productivity of occupants

In certain critical areas like operation theatres and clean rooms IAQ simulations are essential for ensuring compliance to required quality standards

CFD for Power Sector:

Boilers

Fans, Blowers, Pumps, Compressors, Ducts

Electrostatic Precipitators

Turbines

CFD for Automobile Sector:

CFD help in contributing extensively for automobile sector -parametric study (trends), reduced experimental work and others

Numerical modelling is also particularly useful in understanding flow/ looking for bringing qualitative improvements like optimisation of vehicle soiling pattern on windows

The various specific applications of CFD in automobile sector are:

Engine coolant jackets

Under-hood thermal management

Passenger compartment comfort

Prediction of lift & drag coefficient on a car body

In-cylinder simulations in an internal combustion engine

Complete internal combustion engine system like air intake, engine ports and valves, turbo-charger, in-cylinder flow, exhaust & gas after-treatment

Flow organisation, stability & optimisation

Detailed look at flow field, especially in complex geometry

Optimisation of secondary effects - fuel-air mixture preparations

Intake Valve and Manifold

2-D steady-state incompressible turbulent fluid flows.
