Welcome to Our Summer Interns!

Welcome to Our Summer Interns!

Encorus would like to extend a warm welcome to our 2019 summer intern group! We will be hosting four interns in our Springville and Buffalo offices. Noah Wichlacz is a student studying Biomedical Engineering at UB. This summer, he will be working out of our Buffalo office as an Engineering Technician intern. Shannon O’Neill is also working in the Buffalo office as an Engineering Technician intern. After the summer, Shannon will be returning to Penn State Behrend University for her junior year.

Two interns will be joining the Springville office for the summer. Mara Gilmartin is an incoming freshman at RIT, and will be assisting Encorus’s Marketing Department. Jenna Needleman will be supporting the Structural Engineering Department this summer and will return to RIT as a senior in the fall. 

We’re happy to have these wonderful interns working alongside us for the whole summer!

Fun Fact Friday: Air Handling Units (AHUs)

Fun Fact Friday: Air Handling Units (AHUs)

With summer (hopefully) on its way, you may start thinking about the air temperature in your home or office. We’re lucky to have the technology to regulate the temperature and humidity of the air inside buildings. Have you ever thought about the process and equipment necessary to make that happen, though?

According to The Engineering Mindset, air handling units supply and distribute conditioned air throughout the ductwork within a building, usually on a commercial or industrial scale. These units are tasked with circulating air and keeping it at a comfortable temperature. There are two sections of an AHU: supply and return. The supply has more components than the return, which are broken down below.

The first section of the AHU that obtains air in from outside includes a grate to filter out garbage and to keep other foreign objects from entering into the system. The next part of the system includes a damper, which can either open or close, letting air in and out, or preventing air from moving completely. The system then continues with layers of filters, which prevent dirt and dust from being distributed around the building.

Heating and cooling coils follow, which either increase or decrease the temperature of the air depending on the set temperature on the thermostat. The AHUs also control the moisture level within the air. If the air is too dry, the AHU will emit a spray of water into the air before circulating it. If the air is too humid, the humidity is reduced using a cooling coil. Following the heating and cooling coils is a fan, which pulls the air from the outside, and then pushes it throughout the ductwork of the building. This is the basic design of an AHU supply, but some versions include different technology such as heat wheels and air plate heat exchangers.

The return system is much simpler. It usually only consists of a fan to pull the air out of the building, and a damper to either allow or prevent air flow. There is also a grate at the end of the system to prevent animals or garbage from entering into the vents. Although the system is not as complex as the supply system, it is just as important to remove the used air as it is to add fresh air.

The AHU systems are essential to maintaining the internal temperature and appropriate humidity of a building. If you require AHU system design, please contact Director of Engineering Design Tom Gilmartin at (716) 592-3980 ext 124 or tgilmartin@encorus.com.

The Advantages of Finite Element Analysis in Mechanical Engineering

The Advantages of Finite Element Analysis in Mechanical Engineering

From aerospace to healthcare, engineers in every industry are constantly thinking of how to make improvements. Designing new components, materials, and procedures is a process of constant innovation. Before these designs can be used, they must be rigorously tested under real-world conditions to ensure that they work safely and effectively. Instead of testing prototype after prototype, it can be more cost-effective to subject designs to finite element analysis performed by a mechanical engineering service.

What Is Finite Element Analysis?

Finite element analysis involves breaking down the complex geometry of a mechanical component or system into an assembly of smaller (finite) and simpler elements. Each of these elements is modeled in a computer and subjected to mathematical calculations that test everything from the effects of electromagnetism on the component to its response to prolonged heating, physical stress, etc. These calculations are described using partial differential equations that are systematically applied to each element to demonstrate how it would react to real world conditions.

The Three Stages of Finite Element Analysis

Mechanical engineers begin finite element analysis by developing an “element mesh,” a breakdown of the test subject into multiple discrete elements. Then, each element is systematically analyzed in a computer simulation, applying any condition the engineering team deems important and solving equations at numerous data points to create a matrix of information. That range of data is then compiled and analyzed to provide a comprehensive evaluation of the design.

The Benefits of Finite Element Analysis

Finite element analysis lets mechanical engineering firms test, re-test, and recalibrate designs for a new component, material, or process. Breaking down physical structures into groups of smaller elements allows engineers to subject them to a variety of simulated conditions without the need for multiple prototypes. Finite element analysis can be used to test components in situations that would be expensive or difficult to test in a controlled environment, such as a piston design’s response to extreme temperatures or the durability of components in an oil rig under fluid pressure.

Encorus Group offers nationwide finite element analysis as part of our broad range of mechanical engineering services. From municipal waterworks to nuclear power facilities, we can help you rigorously analyze, assess, and perfect your designs to ensure that they will perform as intended. We are proud to be a Service-Disabled Veteran-Owned Small Business (SDVOSB) with decades of experience in the field.
