    Building on a traditional chemical engineering curriculum using computational fluid dynamics
    (Education for Chemical Engineers, 2014-12-01) Adair, Desmond; Bakenov, Zhumabay; Jaeger, Martin; Desmond, Adair
    Abstract Computational fluid dynamics (CFD) has been incorporated into a chemical engineering curriculum at the intermediate undergraduate level. CFD has now become a component of professional life in engineering practice and to prepare students properly, they must get exposure to all aspects of their chosen profession. Issues of concern arise when mathematical modelling is being introduced into a curriculum. For example, at the practical level, it must be considered whether or not an appropriate platform has been developed to allow the students to use the software efficiently and importantly without frustration. Also it is important that students have been taught sufficient skills for the student to continue with simulations in a systematic and methodical manner. The incorporation of the CFD package into a traditional chemical engineering curriculum is described here, and evaluation results based on pre–post knowledge and skill experiments, and student survey results document successful learning outcomes and effectiveness of the approach.

    Simulation of tapered rotating beams with centrifugal stiffening using the Adomian decomposition method
    (Applied Mathematical Modelling, 2016-02-15) Adair, Desmond; Jaeger, Martin; Desmond, Adair
    Abstract The Adomian modified decomposition method (AMDM) is employed for the free transverse vibration analysis of rotating non-uniform Euler-Bernoulli beams using several boundary conditions, rotation speeds, and beam lengths. The equation of motion includes the axial force due to centrifugal stiffening. The AMDM allows the governing differential equation to become a recursive algebraic equation and after additional simple mathematical operations on the model, the natural frequencies and corresponding closed-form series solution of the mode shape can be obtained simultaneously. The AMDM technique is systematic, so it is straightforward to modify the boundary conditions for specific cases. Comparisons with previously reported results demonstrated that the results obtained by the proposed method were in close agreement.
