Derek Lastiwka

Derek Lastiwka’s research focuses on the application of computational fluid dynamics to quantify the performance and losses of a novel ramjet engine design. The numerical tools used for the analyses are the open-source software OpenFOAM and custom created 1D solvers. The development of custom 1D solver allows the group to explore the design space very quickly and then traditional computational fluid dynamics analyses can then verify and fine tune the design. In addition, Derek’s research is closely tied to the experimental groups work which helps provides reliable numerical tools to quantify and guide the design of the engine and testing that the experimental group should focus on. Derek completed his master’s at the University of Ottawa in May 2009. Between 2009 to 2019 he has been working for various engineering consulting companies primarily using numerical tools to aid in the design of machinery in the energy, oil and gas, medical, mining, material processing, and aerospace industries.
