Fluid Simulation

At Fastway engineering, our goal is to empower you with knowledge. By usingutilizing advanced CFD software, we offer you the opportunity to visualize flow in a manner that was previously unattainable. It’s time to say goodbye to guessing and overly simplified estimations of velocities, pressures, and fluid forces, and gain an in-depth comprehension of your design.

What is fluid simulation?

Fluid simulation is the process of using computer algorithms and numerical methods to simulate the behavior and movement of fluids, such as liquids and gases. Utilizing Computational Fluid Dynamics (CFD), fluid simulation involves analyzing an entire fluid volume, the complex physical behavior of fluids, including how they flow, mix, and interact with their surroundings. 

Fluid simulation typically involves modeling the fluid as a collection of particles or a continuous volume, and then using mathematical equations to calculate the movement and behavior of those particles or the fluid volume over time. These simulations can be used to study the behavior of fluids in a wide range of applications, from understanding how fluids move through pipes and channels, to designing aircraft and spacecraft, to predicting the reliability of electronics.creating realistic water or smoke effects in video games and movies.

Why Is Fluid Simulation Important?

The power of a CFD analysis is its ability to visualize the full flow field, which is nearly impossible to do empirically. Before simulation software, engineers would measure flow by submerging the sensors into the fluid, therefore introducing error into the test. By leveraging parametric CAD models, FEA and CFD software can be fully coupled to the design to automatically conduct a full-scale Design of Experiments (DOE). Here are other potential advantages of fluid simulation –

  1. Designing and optimizing fluid systems: Fluid simulation is used extensively in engineering and design to optimize the performance of fluid systems, such as pipelines, pumps, and turbines. By simulating the behavior of fluids in these systems, engineers can identify potential issues and optimize designs for maximum efficiency.
  2. Testing new designs: Fluid simulation allows engineers and designers to test new designs in a virtual environment before building physical prototypes. This can save time and money by identifying potential issues and improving designs before they are built.
  3. Predicting Fluid Forces: CFD allows a design engineer to accurately predict internal and external fluid pressures, to aid in the design and optimization of a structure. Fluid simulation does this by accurately capturing turbulence and other dynamic effects, which are not accounted for in simple hand calcs.
  4. Creating realistic visual effects: Fluid simulation is also used in visual effects and animation to create realistic water, smoke, and other fluid effects in movies and video games. This has become an important tool for creating immersive and realistic visual experiences.

Fluid Simulation For Design Engineers

The complex behavior of fluids and the necessity to predict their behavior in real-world scenarios, makes fluid analysis an essential tool for engineers, scientists, and designers in a wide range of industries. It is a critical tool for design engineers to accurately predict how fluids will behave within their designs. This is particularly important for applications such as aerospace, automotive, and medical device engineering, where the performance and safety of the final product can be heavily influenced by fluid dynamics. 

By using fluid simulation, engineers can test and optimize their designs in a virtual environment before physically building and testing prototypes, saving time and reducing costs. Fluid simulation also allows engineers to evaluate different design options and make informed decisions based on quantitative data, leading to more efficient and effective designs. Overall, fluid simulation is a crucial component of the design process, providing engineers with the insights they need to create innovative and high-performing products.

Benefits of Working With Engineering Experts

It is important to note that CFD analysis is more intricate than Finite Element Analysis (FEA). While solids are consistent in their properties, fluids are complex and their properties can vary greatly. Fluids can have varying densities (compressibility), viscosities (non-Newtonian), and flow types, which can range from laminar to turbulent or even transition between the two states. In certain cases, solid volumes may also be included in the analysis to determine the forces affecting structures.

Our lead designers at Fastway, extract the fluid volume from a client’s CAD software and import it directly into our CFD analysis software. In this process, we assign inlets and outlets, input the known values of velocity, flow rate, or pressure, and establish walls around the fluid. The software then calculates the velocities and pressures at every point in the fluid, and these results are further analyzed using various methods. Fastway’s key value proposition in fluid simulation lies in our ability to interpret and effectively communicate these results to our clients. Our state-of-the-art software and services allow you to easily simulate and analyze fluid dynamics, giving you the insights you need to optimize your designs and reduce costs.
