Computers are used every day to efficiently perform mathematical computations. For engineers to work efficiently, abstraction is necessary; this means hiding lower-level details of an algorithm to emphasize higher-level structure. In this presentation, the fluid exploration with CFD is explored. The presentation is based on a course held at Woodruff School of Mechanical Engineering.

During the past decade reverse engineering has become a common and acceptable practice utilized by many aftermarket suppliers, and even original equipment manufacturers (OEM). This presentation focuses on the applications of multiphysics software such as COMSOL and Simpleware® in reinventing the design details and manufacturing processes of an existing part in the absence of the original design ...

We present an optimization procedure to improve the propagation properties of the depressed-cladding, buried micro-structured waveguides formed in a z-cut lithium niobate (LN) crystal by high repetition rate femtosecond (fs) laser writing. It is shown that the propagation wavelength for which the confinement losses of ordinary (O) and extraordinary ordinary (E) polarizations are below 1 dB/cm ...

Boundary value problems posed over thin solids are amenable to a dimensional reduction in that one or more spatial variables may be eliminated from the governing equation, resulting in significant computational gains with minimal loss in accuracy. Extant dimensional reduction techniques unfortunately rely on representing the solid as a hypothetical mid-surface plus a possibly varying thickness. ...

Tessellated models are more and more used in several engineering fields. The need to use such models to quickly perform computer simulations related to coupled physical phenomena, implies the use of dedicated software, allowing to solve, into an integrated environment, multiphysics problems. In the present work, COMSOL Multiphysics® has been used and its ability to handle tessellated models ...

With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research several different reactor constructions and impeller configurations were modelled to achieve a better ...

We demonstrate cartogram construction, where a geographical map is distorted to represent some measure, for example population, while trying to keep the shape of regions recognizable. We then apply this cartogram construction technique to optimize thermocouple locations. A heat generation and conduction model is used initialize the cartogram construction algorithm. A uniform distribution of ...

In this work a thermoacoustic analysis of a tubular combustor with an advanced lean injection system is presented. The performed analysis is based on the resolution of the eigenvalue problem related to an inhomogeneous wave equation which includes a source term representing heat release fluctuations (the so called Flame-Transfer-Function, FTF) in the flame region. The effect of the mean flow is ...
