Applications of Computational Fluid Dynamics

April 2, 2019

From the external view, we all see industrial equipment as just a sheer assembly of all components. But what goes into manufacturing one is enormous. Assembling components alone are not involved in manufacturing of industrial equipment. Validation is an important part of the process and under validation comes the testing of Computational Fluid Dynamics. Perfect and stunning outer look alone won’t say equipment is fit to be launched in the market. Rather how it reacts to different conditions and is it resistant to untoward incidents. So many tests like finite element method, spectral element method, coherent vortex simulation, direct numerical simulation to name a few are done to ensure each equipment manufactured is in the best of all conditions to make the end user’s ride comfortable. Here are some of the applications of Computational Fluid Dynamics.

Thermal Management

For any product controlling temperature is quite critical. If you’re operating a chemical reactor less than the required temperature the yield turns out to be less. At the same time, too high temperature will make it toxic for the workforce. Hence thermal management test is a must for any industry application. CFD involves a combination of unique simulations and analysis that generates unique results. Several cases are solved based on assumptions and general rules, but for critical cases like thermal management CFD turns out to be more viable.

Cavitation

Pumps, valves, compressors and fuel injectors are often prone to formation of vapour bubbles. It is quite a common challenge and in many cases can pull down the overall performance of the equipment. Excessive noise and vibration is one among the biggest challenges posed by cavitation. Hence to fix this issue, wide of range of CFD analysis and simulations can be utilized. Cavitation is a problem which can be avoided if the design is right. Hence engineers can utilize an array of CFD analysis methods to see the design doesn’t produce a model which is prone to cavitation in any of the relevant components.

Turbomachinery

Improving efficiency of turbochargers and turbopumps is a big challenge for any manufacturer. Experts say improving this performance can actually save billions of money spent on air transport and gas powered electrical industry. Also, performance improvements with regard to safety, operating range, reliability, operating costs and time to market are other set of challenges involved. Accurate simulation is the optimal solution to overcome this issue and CFD applications are the right ones to do so. With CFD, not only your efficiency and reliability increases, but also you can lower your emissions.

Structure Interactions

An important challenge involved in fluid flow management is structural interactions. Interaction of fluid with structures will actually cause damage to some parts and cause deformations. This in turn might change the course of fluid flow. To overcome this, you need to fix this issue in the design stage itself. To predict possible fluid and structural interactions, Computational Fluid Dynamics comes as a problem solver with its optimal simulations and analysis. Hence with CFD, you can better understand the behavior of your product and avoid challenges.

General Process of Fatigue Analysis

October 3, 2018

Before letting a product in the market, every manufacturer runs a stress test on the product to see if it can withstand in any condition and last for long. So a product should be robust enough and should come through all these tests before entering the market. This is a quality analyzing process. Stress test is still a part of the process; there is a more general term that consumes stress test and i.e. Fatigue Analysis. The name might sound clinical, but its significance is not. Fatigue Analysis is to fundamentally test the capacity of the product and how many life cycles it can take. By doing this, you are releasing a product that is way more viable for your target audience to make you relevant for a prolonged time. Here is the general process involved in Fatigue Analysis.

Fatigue Analysis

Time & the No. of Cycles it Should Last

When you make a product you come up with a plan. For example, when you manufacture a battery, you have a time planned for it to last. Your idea will be to let it last for three months. In the contrary, you might even think your product should last forever. But the tiny component comes with limited capacity and every time the one who uses might have to refill the battery. Hence when you manufacture the product, you need to decide how long the product should last.

Stress Analysis for Each Load

When we say each load, it is the cycle it revamps. Let us say the component you manufacture keeps falling down every one year. Hence you have to do a stress analysis for each load i.e. for the each cycle. So you will know how much refill, where to fix, how to fix etc. By doing so, you limit overall damages.

No. of Cycles Each Loading Event in a Cycle Will See

When you reload or refill to revamp the product, you should exactly know the time when the component will fail. So you can approach your clients, get the component and revamp it completely. If you fail to do so, they end up changing it with some other brand. This activity will amp up your relevance in the market.

Find a Fatigue Curve with Correct Loading Ratio to Find Damage Produced by Each Stress Level for Each Loading Event

Times keep changing. We might have a plan, but whatever happens is not going to be as we planned. Hence you should always come with a Plan B to cover up the extra damage. Fatigue Analysis suggests identifying the Fatigue Curve, testing the damage for each stress level and for each loading event. This activity will help you do the right changes while revamping in each and every cycle.

Combine All Damages & Multiply by Desired Safety Factor

Damages in each revamping cycle will differ. Hence you need to keep a note of damages that occurred in every cycle. This will help you ensure that you employ practices to limit the number of damage while manufacturing the next set of components.
