A Brief Overview of Fluid-Structure Interaction Analysis

A Multiphysics link between the principles governing fluid dynamics and structural mechanics is known as fluid-structure interaction (FSI). This phenomenon is defined by steady or oscillatory interactions between a deformable or moving structure and surrounding or internal fluid flow. A fluid-structure interaction analysis (FSI) is performed using computational fluid dynamics (CFD) and finite element analysis (FEA).

The discipline of computational fluid dynamics (CFD) involves using a numerical approach to solve the mathematical equations governing these processes in order to forecast fluid flow, heat transfer, mass transfer, chemical reactions, and related phenomena. On the other hand, the method for numerically predicting how a system or component will respond to a structural or thermal load is called finite element analysis (FEA). 

The fluid-structure interaction is classified into three groups –

1. Zero Strain Interaction which involves the movement of suspended solids in a liquid matrix. 

2. The second is constant strain steady flow interactions. It is about the steady force applied to an oil pipeline as a result of viscous contact between the fluid and the pipeline walls. 

3. Oscillatory interactions are when the strain forces a solid structure to shift which reduces the source of the strain. The structure returns to its former state and the process repeats.

Everything you should know about Blast Mitigation

Image
While there is no way to prevent damage from a bomb blast or explosion entirely, it is feasible to lessen the severity of the effects. In blast mitigation, blast-resistant windows and doors have been utilized for some time in more apparent contexts, but the rise in the frequency with which blast-type assaults or occurrences occur has led to the need for even greater levels of protection in a broader variety of settings. What is Blast Mitigation? Blast Mitigation is a tactical scheme or technique developed to mitigate the after-effects of an explosion, which are brought on by energy forces and pressure impulses. Its purpose is to stop shrapnel, rubble, and buildings from falling during an explosion. Through surface modification, it serves as a corrosion control tool in addition to protecting people, property, and infrastructure. A Brief Explanation of Blast mitigation The explosion releases energy in the form of fragments, sound, shock waves, and other kinds of radiation. While there
