CFD + FEA (Hybrid) Projects : FLUID STRUCTURE INTERACTION

A combination of CFD and FEA simulations can be used to predict the deformation of structures following the force exerted by the surrounding fluid flow.The results(pressure values) obtained by the flow analysis can be used as input values(force value) for the structural analysis. This technique can be used to get very accurate results in the following sectors.



Heat Exchange Optimization

The Heat exchanger's critical purpose is to involve in transfer of heat between multiple s ources. Problem definition of this equipment covers cyclic usage & Thermal loadings in the industrial applications. Problem area's being adverse environmental exposure and seismic loading. The criticality is addressed with combination of CFD and FEA where Fatigue and Vibration requirements are been resolved.

Optimization of Inductor Panel box-SOOKVA

The function of the Inductor Panel Box to control and regulate the power supply to AC units. Due to the function & location of the Inductor Panel Box, it need to withstand large thermal and dynamic stresses. The existing design has to be optimized to withstand these stresses.

  • 1) The project involves CFD analysis to compute the flow pattern which would then be used in thermal analysis.
  • 2) The data from the CFD analysis is then used in the structural & thermo structural analysis.
  • 3) Shock & fatigue analysis was also carried out.

    Seismic Analysis of Fuel tanks

    The objective of this project is to study the effect of various components of earthquake on sloshing response of liquid storage tanks. The Finite Element Modelling (FEM) strategy which was used to simulate dynamic response of the liquid tank system was described. The FEM was validated using a set of manual calculation which is used in available design guidelines. As per the seismic standard the model has been validated at different G value in vertical, cylindrical ground supported tanks with different aspect ratios excited by various time series of earthquake accelerations was performed.

    Conclusion :

    Based on the analysis, significant changes were made on the design. The redesigned product successfully withstood both thermal & dynamic stresses in accordance with the IEC standards
