Turbomachinery is widely used in industries for versatile applications. Energy transfer is caused by the  dynamic motion between the rotating element and flowing fluid leading to change in pressure and momentum. These are geometrically and operationally complex machinery. 3D modeling of turbomachinery includes thermodynamics, severe changes in velocity, pressure and momentum, compressible flows, angular momentum. Dynamic meshing and fluid solid interaction adds more complexity to these flows. Paanduv has gained expertise in such systems and holds confidence to address high level of complexity for turbomachinery.

Compressors are used in chemical, mechanical fields where a compressible fluid or gas needs to be pressurized. This operation is performed by reducing the volume. These are complex machinery with high degree of structural, meshing and solver complexity. CFD is a powerful tool to deal with turbomachinery.

Rotary and reciprocating positive displacement compressors and centrifugal compressors are modeled using computational fluid dynamics.


The design of the impeller is crucial for reactors, compressors, and pumps. It hampers the mixing patterns in a reactor and can also minimize the dead zones. No of blades, orientation angles, and axial placement of the blade are some of the parameters which are modified to optimize the mixing in the chamber.  

Maintaining homogeneity, and increasing velocity with a reduction in pressure is the prime job that an impeller does. Based on the application the design of the impeller, spacing between the blades, thickness, and material of construction changes. Modeling of such systems uses CFD as its core simulation tool.

Turbine Blade

Turbine blades are designed for the production of electricity. These are generally two or three-blade turbines attached at a horizontal axis converting wind energy into torque. Which then translates to Nacelle which converts this torque into electrical energy. 

The design of blades (flat, curved, or bent), their aerodynamics, lift and drag quantification, and dimensions is optimized using CFD. Dynamic meshing poses additional complexity in these systems. We provide accurate solutions to problems to such problems.
