Precision in Motion: Optimizing Pump Performance Through Rotodynamic Analysis
Introduction Rotating machinery is the backbone of modern industrial applications, from pumps, turbines, and compressors to generators and high-speed spindles. However, as operating speeds and loads increase, so do the challenges associated with vibration, resonance, unbalance, and fluid-induced instability. Without proper analysis and optimization, these issues can lead to: At SDEA Solutions, we specialize in […]
Vibration Induced Fatigue Failure in Process Pipework
Piping Vibration and Fatigue Failures Piping Vibration is the cause of fatigue failures of pipework. This leads to important issues due to the rupture of components, such as welded joints associated with main lines and small-bore connections. When talking about piping vibrations, two main types can be distinguished, flow induced vibration (FIV), and acoustic induced […]
When Tanks Visibly Bulge: Tackling the Aesthetic and Structural Challenges of Atmospheric Storage Vibrations
Dynamic Bulging in Atmospheric Storage Tanks 1. Introduction to dynamic bulging: Atmospheric storage tanks are critical in industries ranging from oil and gas to chemical processing, designed to safely contain large volumes of liquids. However, a non very common but often overlooked issue is the visible dancing bulging that can occur during filling and emptying […]
Solving a Thermal-Mechanical Problem in Hydroforming L-Foot Fins for Heat Exchanger Tubes Using Finite Element Analysis
Heat exchangers and condensers are an essential component in many industries, such as chemical, power generation, and refrigeration. They transfer heat between two fluids, which can be gases or liquids, without them coming into contact with each other. Heat exchangers are designed to maximize heat transfer efficiency while minimizing the size, weight, and cost of […]

Bellows Expansion Joint Analysis using FEA
This example is a heat exchanger with a bellow expansion joint and the reason of performing this study is because of a transition zone between two parts with different thickness, in order to assess the failure risk in that zone.
Pressure Vessels Design
Pressure Vessels are used in the industry to store process fluids under certain temperature and pressure conditions. Commonly, pressure vessels have cylindrical or spherical shape, can be disposed in a horizontal or vertical way and are provided of heads with different shapes (Ellipsoidal, Hemispherical, Toroidal, etc.). These equipments are fitted with different elements such as nozzles (used […]
Thermal Stress Analysis Of Dissimilar Welding Joints using FEA
Finite Element to foreseen residual stress from the welding process Most welding process involve local heating, therefore temperature distribution is not uniform and structural thermal stresses beyond the material yield [strongly dependent on the temperature] show up, which can create issues on the final design related to fatigue or even geometry distortions. This local temperature […]
TLD Tuned Liquid Dampers
FEA for TLD Tuned Liquid Dampers One of the greatest challenges when it comes to design steel stack structures such as chimneys, is to deal with oscillating loads as dynamic wind forces and seismic spectrum, as commented in this article. These loads threaten the design with coupling the excitation with its natural frequency, leading the […]
FSI Steel Stack Structural FEA Analysis
Chimney miniature When designing steel stack structures, several rules from standards as “ASME STS-1” or “ASCE 7” have to be taken into consideration to assure security during its useful life. This is particularly important for those located in areas subjected to heavy environmental loads, such as high activity seismic zone 4, due to the slender […]
