Identify areas prone to excessive stress or strain in critical components like turbine blades, Boilers and pipelines. Our engineers do these types of analyses using standard like ASME Section VIII and Division 2.
To achieve better strength to weight ratio, now industry is moving towards Fiber reinforced plastics from steel to construct tower structures. Our FE analyst does seismic assessment as per ICC EC AC 156 code. Here, earthquake loading that the cooling tower would have to sustain is replicated by performing response spectrum analysis.
As turbines spin at very high speeds, minor imbalances or vibrations can become magnified at these speeds, leading to catastrophic failures. Our FEA engineers can study the excessive vibrations at extremely high speeds by performing rotor dynamic analyses in order to prevent failures.
Blade undergoes various loading like gravity, centrifugal forces due to rotation and static pressure developed across inlet and outlet, studying these factors our FEA engineers analyze the root cause of failure.

Multiphysics Simulation
Power generation equipment involves complex interplay between fluids like gases or water and the structures that contain them. Traditional FEA might analyze stresses, but without considering the fluid's influence like pressure & heat transfer. Similarly, CFD might analyze flow patterns, but wouldn't account for how the structure itself deforms under those forces. Tridiagonal can bridge this gap by coupling both technologies.
Thermal expansion and contraction can lead to stress and fatigue in boiler tubes and heat exchanger components. Our CFD engineers model the fluid flow and heat transfer within the boiler or heat exchanger. While our FEA engineers can then analyze the resulting thermal stresses and predict areas susceptible to failure or deformation.
Uneven temperature distribution and thermal stresses are observed in incinerator combustion chambers. Our engineers use CFD to simulate the combustion process and heat distribution while FEA, is used to assess the structural integrity and also to identify areas of high stress due to thermal gradients.
Wear and tear on conveyor systems, hoppers, and chutes is observed due to the abrasive nature of coal particles. Tridiagonal Discrete Element Method(DEM) engineers can simulate the movement and interaction of coal particles, while using FEA the structural wear and tear on the handling equipment can be assessed.
