Dynamic analysis of a Variable Displacement Oil Pump shaft under crankshaft torsional vibrations and internal pressure evaluated via CFD
The subject of analysis is a vane oil pump for truck applications. This product represents new generation oil pump in automotive industry thanks to the possibility to reduce the displacement at high engine speed for fuel save consumption.
Using Flowmaster to Prevent Pressure Surge for Water Injection Systems in the Offshore Oil & Gas Industry
Surge pressure, (Water Hammer), is an important design consideration for water injection systems in the Offshore Oil and Gas Industry. The one-dimensional system-level approach provided by Flowmaster is comprehensive and effective from an engineering perspective.
A Multi-Physics Approach to Reduce Fuel Consumption in Aero Engines
The recent evolutions of aeronautic engines require increased efficiency in order to reduce fuel consumption and to meet the targets of future emission levels. A high gas turbine efficiency can be achieved by means of a performing blade designs as well as by a proper management of mass flows during the entire engine flight.
Extreme Ensemble under Uncertainty
The development of robust design strategies coupled with detailed simulation models requires the introduction of advanced algorithms and computing resource management tools. On the algorithmic side, we explore the use of simplex-based stochastic collocation methods to characterize uncertainties, and multi-objective genetic algorithms to optimize a large-scale, three-dimensional geometry using a very large number of CFD simulations on HPC clusters.
ECS System Simulation - Architecture and Performance Optimization from the Early Phases of the System Design
In today's aircraft thermal design, we can observe a trend towards electronics systems integration characterized by higher heat densities and a more frequent use of composite primary structures. All these factors require robust thermal management and thermal architecture design already at the preliminary design stages. The thermal architecture will have to be developed in order to mitigate thermal risks.
Analysis of the Sloshing of a Large Tank with Fukushima Daiichi Seismic Excitations
The Westinghouse AP1000 nuclear reactor design is a pressurized water reactor with a power rating of 3415 MWt and an electrical output of at least 1000 MWe.
The AP1000 design contains a variety of engineering and operational improvements providing additional safety margins and addresses the U.S. NRC severe accident, safety goal, and standardization policy statements.
Thermal Cyclic Stress Analysis of a Solid Rocket Motor
A three-dimensional stress analysis of a rocket motor under cyclic temperature loading was performed. The novelty of the analysis lies in the use of a propellant constitutive model that accounts for the effects of viscoelasticity, large deformation, temperature, pressure, and softening in monotonic and cyclic loadings.
The AP1000 design contains a variety of engineering and operational improvements providing additional safety margins and addresses the U.S. NRC severe accident, safety goal, and standardization policy statements.
Using CAE to Optimize the Structure of Power Harrows for Farm Equipment
One of the goals of the collaboration activities was to increase the viable working velocity of the harrow since higher speed means less time which equates to a fundamental valueadd in the customers’ perception. From the technical point of view, the study was concerned with optimizing the strength of the harrow tooth by looking for the best compromise between the mechanical resistance of the tooth and its mandatory function as a failsafe in the overall transmission chain. In fact, as a cheaper and easily replaceable part, the tooth is required to be the first component that breaks in the case of an extreme impact with an object such as a stone, which can easily occur while working the ground.
