Analyzing a Supersonic Ejector with CFD Simulation

Caty Fairclough April 16, 2018

Ejectors have many applications, such as removing debris in outer space and providing refrigeration at your local supermarket. To improve ejectors for these and other uses, engineers aim to find optimal designs and operating conditions as well as accurately describe the flow within these devices. Simulation can help achieve these goals.

Since their development in the 1960s, subminiature version A (SMA) connectors have become a staple in the RF and microwave industries. The use of these connectors is so widespread, they might even be the most popular RF and microwave connector systems on Earth. To evaluate the performance of an SMA connector, engineers can use the COMSOL Multiphysics® software.

Additive manufacturing has a wide array of applications, such as creating custom medical devices, aerospace components, and artwork. With the list of potential uses continuing to grow, it’s important that this type of manufacturing can keep up with the demand. However, analyzing and optimizing this complex process can be difficult. What can engineers do to overcome this challenge?

In 1801, the building around a glassmaker apprentice named Joseph von Fraunhofer collapsed, trapping him in rubble. While he didn’t know it at the time, this dramatic event (and resulting encounter with a prince-elector and politician) set him on the path toward improving the field of optics…

Due to their inherent versatility and wideband frequency response, spiral slot antennas have a variety of applications for different microwave frequency bands. For example, these antennas are used for wireless communication, sensing, positioning, and tracking. To optimize the design of spiral slot antennas, engineers can use electromagnetics analysis to accurately calculate characteristics such as S-parameters and far-field patterns.

To treat atherosclerosis, a cardiovascular disease in which a buildup of plaque causes an artery to narrow, doctors can insert a tiny wire mesh tube called a stent into the obstructed artery. Expanding the stent opens up the artery and helps restore blood flow. To successfully perform this operation and minimize potential health hazards, stent designs must be thoroughly studied and optimized. To do so, we can perform a nonlinear structural mechanics analysis with the COMSOL Multiphysics® software.

Due to their flexible fuel choice options, immovable parts, and potential for efficient power generation, thermophotovoltaic (TPV) systems have a wide variety of possible applications. For instance, these systems could help provide portable energy, advance space travel, and power automobiles. However, engineers must first improve the efficiency of TPV systems as well as reduce system costs and device temperatures. To accomplish these goals, engineers can use simulation to analyze and optimize their TPV designs.

Micromirrors have two key benefits: low power consumption and low manufacturing costs. For this reason, many industries use micromirrors for a wide range of MEMS applications. To save time and money when designing micromirrors, engineers can accurately account for thermal and viscous damping and analyze device performance via the COMSOL Multiphysics® software.

While our daily lives are clearly affected by the “flashier” parts of the water cycle (rain, snow, etc.), other parts of the cycle — such as the groundwater moving beneath our feet — are just as important. We use groundwater for irrigation and drinking water, and it affects natural processes and habitats. When studying groundwater, it’s often important to understand the movement of various solutes through the water. To predict solute transport, scientists can use multiphysics simulation.

11 light-years away from our solar system, an exoplanet called Ross 128 b orbits a red dwarf star. This planet has the potential to support life and is the second-closest temperate planet discovered, with a surface temperature that might be similar to Earth’s. Astronomers detected Ross 128 b by using data from an échelle spectrograph called HARPS. To further advance the search for Earth-mass exoplanets, we can improve the sensitivity of échelle spectrographs using the COMSOL Multiphysics® software.
