FLOW / CFD ENGINEERING

Fluid flow is one of the essential branch of engineering which make the world's energy flow.   The availability of reliable solution to Navier-Stokes equations coupled with mass, momentum and energy equations allows us to solve various real life engineering flow problems. The approximate solution to Navier-Stokes equations helps to solve various type of practical flow problems. Computational Fluid Dynamics (CFD)  has evolved from theoretical tool to a practical real life problem solving tool. Separated, unsteady and vortex dominated transitional flow simulations for industrial innovation is the growth trend. We provide computational fluid dynamics simulation solutions to predict flow performance of air to water to complex fluids such as polymers, mixtures, multiphase and granular materials for aerodynamics, building ventilation,  electronic cooling, filtration, flow control and material processing. CFD simulations includes laminar, turbulent, high mach, multiphase, non-isothermal, reacting and coupled flows.

Computational  Fluid dynamics deals with the flow of open and closed system to predict the flow pattern, pressure distribution, fluid forces, temperature and  variation in fluid constituents under steady state or transient conditions.  The velocity, pressure and viscosity are the basic flow parameters. The conservation of mass, momentum and energy governs the constitutive behaviour. Simple calculations of Reynolds number, Mach number and Grashof number, provides great initial insight into the nature of flow problems.  CFD provides greater insight and visual details about the flow than experiments, leveraging parameters such as average flow, pressure, lift and drag coefficients, Shear stress and fluid forces.  CFD is used for design of Airfoil for maximum thrust and minimal drag, Virtual wind tunnel experiments, Polymer and complex fluid processing, Pipe flow optimization, Turbomachinery: Turbines, Compressors, combustors and Water treatment and filtration. At ATOA, Computational Fluid Dynamics for product and process innovation for our clients is our ultimate objective.
