Background
Our products are built on a history of industry leadership dating back to the early 1960s when we developed the first commercial Hot Isostatic Press (HIP). Today, Quintus’s technological innovations have expanded HIP-processing parameters to encompass higher pressure and temperatures with unmatched control, and increased capacities. We develop products from research sizes up to the
Hot Isostatic Presses employ pressurized heated gas for consolidation, densification, or bonding of high-performance components and materials. Processed parts can achieve 100% of maximum theoretical density, resulting in exceptional resistance to fatigue, impact, wear and abrasion. The products from the presses are used in a wide range of industries, with applications ranging from plane bodies (aircraft fuselages and fuselage members), aviation engines, car engines, human-body implants, to critical components used in oil and gas. To obtain superior and reliable material properties the HIP operates under extreme conditions with pressures reaching up to 3100 bar and temperatures of up to 3000°C. The combination of such extreme conditions and vessel sizes reaching more than 2 meters in diameter and more than 4 meters in height results in massive amounts of stored energy. In fact, at these temperatures and pressures the ideal gas law no longer applies!
The furnace is the heart of the HIP system and Quintus provides state of the art furnace design with a wide range of styles, hot zone materials and advanced temperature measurement techniques. Quintus has developed its exclusive Uniform Rapid Cooling (URC®) furnace that uses either an ejector or a variable speed fan to circulate cooler gas uniformly throughout the work zone. Today this is the state of art for the customers demanding uniform cooling of their products for productivity and performance benefits. Quintus continued to push the boundaries for HIP with the introduction of production scale Uniform Rapid Quench (URQ®) systems in 2017, and the introduction of a new generation of forced convection furnaces in 2019. These product advancements are the next steps for broadening the use of HIP in new application segments. To meet future market demands, technological advances in HIP are creating a new generation of applications, which needs further development of the furnaces but also application support and testing.
Task description
During the end segment of a cycle a fraction of the gas is dumped out in the atmosphere. The type of silencer, wind, gas flow and height will influence the mixing of argon and the surrounding air. This must be mixed in a way so it’s a safe environment on the ground level. Currently the height is decided depending on local conditions which in some cases can lead to a re-location of the silencers after the commissioning with delays and extra cost as result. We therefore suggest a project aimed to investigate the parameters influencing the exact mount location of the silencers with help of CFD. The aim is that this will be used to decide the location of the silencers in the whole HIP-range from Quintus.
The main tasks will be:
- Transient and steady state analysis of the flow field around the silencer and species mixing with surrounding air
- Validation case of species transport
- Determine how the mixing is influenced by different flow and geometrical parameters
The thesis will give a clear view of how the practical placements matches an optimized placement.
Suitable background
