Engineers are taught to create designs that meet customer specifications. When creating these designs, the focus is usually on the nominal values rather than variation. Robustness refers to creating designs that are insensitive to variability in the inputs. Much of the literature on robustness is dedicated to experimental techniques, particularly Taguchi techniques, which advocate using experiments with replications to estimate variation. This course presents mathematical formulas based on derivatives to determine system variation based on input variation and knowledge of the engineering function.

Today's transportation industries are facing multi-disciplinary challenges. The product design and development process challenges often contradict each other, for example cost, weight, quality and performance. A central challenge is the need for cost and mass reduction to compete in the global market, while continuing to meet all new and existing requirements for quality and performance. Accelerated Concept to Product (ACP) Process is a performance-driven, holistic, product design development method intended to create a balance between structure and strength, synchronizing the individual facets of the product development process.

Commercial vehicle aerodynamics and fuel economy are greatly affected by transient and interfering flows. As the aerodynamic sophistication of commercial vehicles increase the importance of these phenomena in vehicle design will increase. Specific topics to be discussed are guidelines and methods for the modeling and simulation of these effects in vehicle design, experimental evaluation and the operational performance of commercial vehicles.

For aerodynamic technology to mature it is critical that the use of aerodynamic tools is based on critical governing aerodynamic and fluid dynamic criteria. In aerodynamics the most critical criteria is Reynolds number. Specific topics to be discussed are guidance and methods for Reynolds number and boundary layer assessment, modeling and simulation for aerodynamic evaluation and operational performance of commercial vehicles.

To manage design complexity and deliver innovations while reducing development time and improving quality, companies are turning to math-based models and a process known as Model-Based Design. Engineers use an executable specification to iterate through design concepts for the system and/or embedded controls using simulation. The specification then serves as the basis for model-based early verification, in-the-loop testing, and production code generation.

Three dimensional Navier-Stokes simulations of the Honeywell ALF502 low pressure compressor using the NASA Glenn code Glenn-HT have been carried out. A total of eight operating points were investigated. These operating points are at, or near, points where engine icing has been determined to be likely. The results of this study are expected to be used immediately, and in the future, for further analysis such as predicting collection efficiency of ice particles and ice growth rates at various locations in the compressor. A mixing plane boundary condition is used between each blade row, resulting in convergence to steady state within each blade row. Results for two levels of approximation are discussed. The first set of cases were run allowing all of the solid surfaces to slip (i.e. inviscid). That is, the velocity boundary layers are not resolved. This allows for much smaller grids and shorter run times.

Atmospheric icing resulting from freezing rain, freezing drizzle and freezing cloud droplets occurs when airborne supercooled water drops freeze on objects they encounter. This process is especially hazardous to aircraft, when the build-up of ice changes the stability and control characteristics of the aerodynamic surfaces. Ice can also be shed with disastrous consequences, if it is ingested into engines, strikes the aircraft or leads to unbalanced aerodynamics forces. Ice accretion is a complex phenomenon involving 3-D multi-phase flow, heat transfer, and gravitational, viscous, surface tension and shear forces. An ability to predict how ice accretes on engineering structures is essential to the prediction of its associated aerodynamic penalties. We have developed an original icing modelling capability, called the “morphogenetic” approach, based on a discrete formulation and emulation of ice formation physics.
