The Importance of CFD in Modern HVAC Simulation
Introduction Heating Ventilation Air Conditioning (HVAC) systems have an abundance of applications in today’s world. They keep astronauts alive in space [1], prevent infection in operating rooms by maintaining 25 air changes per hour [2] and preserve artworks in museums by stabilising conditions to 20degC (68degF) and 50% relative humidity all year round [3]. As […]
ENGYS Announces Sponsorship of the Hanseatic Efficiency Team at the University of Rostock
ENGYS has entered a sponsorship agreement with the Hanseatic Efficiency team, an interdisciplinary student group from the University of Rostock, Germany. The team designs and builds highly efficient prototype vehicles to compete in the Shell Eco-Marathon, one of the leading global competitions dedicated to energy-efficient mobility. As part of the collaboration, ENGYS will provide access […]
Why Motorsport Teams Trust HELYX For CFD Solver Performance
The ambition of every race team is simple: develop the fastest car possible within the regulations. Achieving this however is a monumental challenge, particularly when those regulations continue to squeeze budgets, resources and testing time. So how do teams continue to improve the aerodynamic performance of their race cars to stay competitive, whilst abiding by […]
The Techniques Driving HELYX’s High Performance Coupled Solver
Whether you are a motorsport aerodynamicist squeezing the most simulations out of a limited budget, time and regulations; or a wind engineer modelling city-scale domains, a high-performance CFD solver is key to simulation success. That’s why ENGYS have spent the last decade relentlessly developing and refining the HELYX-Coupled solver, which now enables the HELYX and […]
Planqc Brings Quantum Computing to Aviation on Behalf of DLR QCI – with TUM, ENGYS and Airbus
How can quantum computers improve aircraft development and make aviation more sustainable? That is the question quantum technology company planqc, together with the Technical University of Munich (TUM), software provider ENGYS, and aerospace company Airbus, aims to answer. The project is carried out on behalf of the German Aerospace Center’s Quantum Computing Initiative (DLR QCI). […]
How Open-Source CFD Can Improve Your UAV Aerodynamic Design Process
From hand-sized nano drones to 18 metre wingspan military UAVs [1], the endless applications of modern drones have led to an abundance of configurations, ranging from single rotor and multirotor to fixed wing and fixed wing hybrid VTOLs (Vertical Take Off and Landing). However, each comes with its own aerodynamic challenges, that need to be […]
Achieving High-Quality, Low-y+ CFD Grids With ENGYS’ Advanced Mesh Algorithm
Skin friction drag can account for up to approximately 30 to 40% of the total aerodynamic drag of a streamlined vehicle [1] and around 45% in subsonic aircraft [2], to name a couple examples. This is why accurately capturing the physics of the boundary layer in Computational Fluid Dynamics (CFD) is critical for determining realistic […]
