Computational Fluid Dynamics

Spray and Atomization

Spray has a big part in modern industry and even daily household applications.  Break-up and atomization is a complex process. Spray flows are subject to high shear forces and even reacting flows around. Reacting flows can be solved for using Euler-Euler or Euler-Lagrange methods. Which approach is more suitable depends on available computational power and type of application. We can help you analyze spray flows (using open source or proprietary software) within atomizers, gas turbine combustion chambers, internal combustion engines, rocket motors etc.

Aerodynamic/Hydrodynamic Flows

Aerodynamics/hydrodynamics is the branch of science that deals with forces acting on solid bodies as a result of airflow/waterflow around them. When solving aerodynamic flows using CFD methods, forces and moments acting on the body are calculated. This data is further processed to yield necessary aerodynamic/hydrodynamic coefficients that can be fed into six-DOF simulations. At Melina Aero we can perform such virtual wind/water tunnel simulations for our customers.



Reactive Flows

Fossil fuel combustion accounts for 85% of worldwide energy production. Thermal power plants, automobiles, aircraft are examples of energy conversion devices that convert chemical energy into either electrical or mechanical energy. Combustion phenomenon lies in the core of this conversion mechanism. Therefore reacting flows have a wide area of application ranging from internal combustion engines, gas turbines, furnaces and even rocket propulsion. It is possible to analyze these types of flows via CFD methods.

Modelling and Analysis

Performance Analysis of Gas Turbines

Conceptional design of a gas turbine engine involves performance cycle analysis within the operational envelope of the engine (design point and off-design point). We can handle these types of studies using third party package programs and/or using tailor made in-house codes that we develop.


One Dimensional Modeling of a Flow Network

Fluid flow and heat transfer within a combustion chamber of a gas turbine engine may be analyzed generally without using detailed computational fluid dynamics (CFD) methods. This provides a means for quick optimization of liner geometry, cooling hole diameter, count and position. Liner temperatures and emissions trends can be estimated fairly quickly (within seconds). The optimized design alternatives can further be examined using detailed 2D or 3D CFD calculations. Even the flow in complex piping systems (city water networks, gas networks and pipelines) can be handled with this method.

Modelling a Thrust Vector Control (TVC) System

Thrust vector control system enables an air vehicle to alter the direction of its trust vector. Thus, the necessary moment to turn the air vehicle is provided by shifting the direction of thrust vector from the main axis of the vehicle into another one. This method is independent of ambient pressure, hence great forces can be obtained even at low velocities and high altitudes. Therefore, great maneuverability capability can be obtained with a thrust vector control system. This system is commonly used in some fighter jets and many guided missiles. We can provide modeling and simulation services in this area.
