Reaction Engineering with Advanced Simulation
In our last webinar , we looked at how simulation can be utilized in the design and scale-up of various reactors. In this webcast, we continue to investigate the multiphase flow phenomenon within reactors in more detail. For example, in a trickle bed reactor the flow regime depends on many complex factors; if not accounted for this can lead to poor micro and macro distribution, resulting in catalyst activity loss and failure to meet product specifications. The webcast addresses looking at advanced modeling methods to uncover such phenomena. Many mixing vessels may develop deep vortices, these...
Full System Simulation of a Micro Gas Turbine
Micro turbines represent a promising solution to the continuing global search for more reliable, affordable and safer access to cleaner energy. They meet this environmental challenge by producing enough distributed combined-heat-and-power (CHP) to satisfy residential-level demands for heating and electricity. In addition, they must produce emissions and noise at acceptably low levels. This webcast focuses on how CFD/CHT simulation was used to discover better designs faster, ultimately yielding a highly reliable and cost-efficient micro turbine capable of generating 3kW of power. Topics to be...
Aero-vibro-acoustic prediction of interior noise associated with exterior flow requires accurate predictions of both fluctuating surface pressures across the exterior of a vehicle and efficient models of the vibro-acoustic transmission of these surface pressures to the interior of a vehicle. The simulation strategy used in this paper combines both CFD and vibro-acoustic methods. An accurate excitation field (which accounts for both hydrodynamic and acoustic pressure fluctuations) is calculated with a hybrid CAA approach based on an incompressible unsteady flow field with an additional...
wave6 is a standalone frequency domain simulation software package for modeling the transmission of noise and vibration through complex systems across a broad frequency range.It was developed in conjunction with wave six and combines CD-adapco’s expertise in flow simulation with wave six’s knowledge of noise and vibration simulation.
CD-adapco, the largest privately held CFD-focused provider of Computer Aided Engineering software, announced today the release of STAR-CD and es-ice v4.24, the latest update to its industry-leading Internal Combustion Engine (ICE) simulation solution. This release forwards CD-adapco’s mission to help their customers discover better designs faster with improved usability, increased accuracy and automation for ICE simulation.
The research project in question uses the regulations as provide by the Society of Automotive Engineers (SAE) for their yearly racing event Formula SAE (FSAE) competition in Michigan (2015 FORMULA SAE RULES. (2014). SAE INTERNATIONAL).The objective is to develop a full aerodynamic package to be produced by the Indiana- university Purdue- University Indianapolis (IUPUI) Formula SAE team in the spring of 2015. The term ‘full aerodynamic package’ consists of the following. A nosecone to cover the front of the car designed to generate ‘downforce’ or reverse lift. An engine cover designed to...
Expanding the Boundaries of Multidisciplinary Analysis with Fluid Structure Interaction (FSI)
From the bending of a tree branch in the wind to the flexing of an aircraft wing as it crosses the Atlantic, fluids and solids interact in harmony everywhere in the real world. However, in the virtual world of engineering simulation, the picture has rarely been in concert. Structural analysis and fluid dynamics, although intrinsically linked, have long been quite separate disciplines with the interaction between deforming structures and flowing fluids usually being considered at a most basic level. The picture is changing, however, as innovative simulation tools are providing a better...
In the separation process of an emulsion, smaller droplets grow in size due to binary coalescence and simultaneously sediment/cream due to gravity. Finally, droplets coalesce at a homogeneous interface due to interfacial coalescence. Even the above simplified description of separation introduces several requirements for the modelling of such processes: • Relative motion between phases of different properties. • Free settling of droplets, with possibility of stratification owing to different sedimentation velocities. • Formation and behavior of a dense packed layer (DPL), ultimately leading to...
