  • How to Convince Your Manager to Adopt Simulation Software

    Evidence from many competitive companies shows that employing simulation allows significant optimization of the design processes to deliver better products in a much shorter period of time. If you are an engineer struggling with generating support from your manager who doesn’t see the value of engineering simulation software, you are not alone. The most commonly cited…

  • Cross Flow Fan – Testing Vibration and Aerodynamics with CFD

    The cross flow fan (also called a tangential fan) is used extensively in the HVAC industry, as well as in electronics. It produces an even laminar airflow and allows horizontal or vertical mounting; in addition, a cross flow fan prevents the overheating of components. This type of fan is ideal for limited spaces, due to its…

  • Centrifugal Fan CFD Analysis for Predicting its Aerodynamics

    The centrifugal fan (often called squirrel cage fan) is a mechanical device specifically designed to move air or other gases. Due to their simple design, centrifugal fans are more easily manufactured than other types of fans, which renders them more time- and cost-effective to produce. This makes centrifugal fans a popular choice for air-handling applications. Their rotating impellers…

  • Testing the Cooling Performance of a Heat Sink for Different LED Packages

    A heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, where it is dissipated away from the device. By allowing the heat to dissipate, the heat sink prevents overheating and plays a crucial role in the device’s temperature regulation. Heat sinks…

  • Conjugate Heat Transfer Analysis on a Raspberry Pi

    A heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, where it is then dissipated away from the device. Through this process, the heat sinks play a crucial role in the temperature regulation of the device, preventing overheating. Heat sinks are…

  • Active Compared to Passive Ventilation Using CFD: IBEEE’s Story

    Rising energy prices, environmental consciousness, and the associated demand for energy efficiency are key considerations in the design of single and multi-family houses, in an attempt to reduce the ecological footprint. One of the trends for increased efficiency in housing is passive houses, which don’t require classical building heating due to their excellent thermal insulation.…

  • Carbon Wheels Simulated with SimScale | Tokyowheel’s CFD Story

    “Ride Faster, With Less Effort, and Enjoy Your Cycling More.” This is the promise the people at Tokyowheel make to their customers. And they stand by their word. Seven years ago, carbon carbon fiber wheels for bikes were reserved only for the rich in Japan, as the price for a decent set was no less than a…

  • 10 Piping Design Simulations: Fluid Flow and Stress Analyses

    Piping design is essential for a wide range of applications, from oil and gas extraction and transportation to refineries, power stations, HVAC, plant engineering and cooling systems in engines and turbines. To ensure the functionality of the piping networks and improve their performance for fluid transportation, process engineers need efficient tools and solutions for piping…

  • What is Accuracy in FEA or CFD Simulation?

    This is a common question that haunts most designers: what is accuracy in FEA or CFD simulation? And just how accurate are these computer models? With rapidly advancing technology and growing computer power, simulations have started to play a major role in product design and the optimization process. In the early days of modern technology,…

  • What is Convergence in Finite Element Analysis?

    A typical engineering design involves the prediction of deflections/displacements, stresses, natural frequencies, temperature distributions, etc. These parameters are used to iterate on material parameters and/or geometry to optimize their behavior. Traditional methods, like hand calculations, involved the idealization of physical models using simple equations to obtain solutions. However, these approximations oversimplify the problem, and an…

  • 5 Ready-to-Use CFD Simulations for Aircraft Design

    A few decades ago, aerospace became the first industry to embrace engineering simulation. From nanotechnologies and micro-composite materials to futuristic wings profiles, many research projects in aircraft design focus on finding better solutions and bringing them to market faster, while simultaneously reducing costs. Using engineering simulation software as part of their development process, aerospace companies…

  • What Is Modal Analysis and Why Is It Necessary?

    We often hear the terms “modal analysis,” “eigenvalues,” “eigenmodes” or “eigenfrequencies”, and by the time one comprehends a single terminology, a new terminology emerges. People always prefer to make things sound more complicated than they need to be. More often these terms develop out of necessity, but many times it’s to express things with mathematical…
