DOIĬFD modeling of methane-air combustion and the subsequent flame and pressure wave propagations from the closed end of a detonation tube is presented, with a focus on propagation through variable concentration mixtures. This study has critically assessed highly cited correlations, delivered a comparative analysis of their applicability and predictability against a large pool of experimental data, and deepened the understanding of parameters that affect the prediction of Umf(mixture) using different correlations. effective size and density), flow conditions, and solids composition. The limitations of these correlations are often expressed in terms of particles properties (e.g. Many correlations exist for predicting Umf(mixture) however, they exhibit limitations in accuracy and/or applicability. The design and operation of such systems heavily rely on the prediction of minimum fluidization velocity of the mixture (Umf(mixture)) to avoid particle segregation and maximize mixing. Gas fluidized beds with bi-dispersed particles of different sizes, densities, and shapes are encountered in many industrial processes spanning the manufacture of energy, material and resources to greenhouse emissions mitigation and renewable resources utilization. It lays the foundation for subsequent courses studied in the following years. In this course students are introduced to fluid mechanics concepts and their application in a range of engineering contexts. Also provides students with the fundamentals necessary to design or evaluate a broad range of separation processes.Ĭollege of Engineering, Science and Environment, University of Newcastle Most of the model development is based on simple unit operations and separation processes. Provides an understanding of simple model development, transfer functions, block diagram representation and analysis, and simple control systems.

Dr Peng strives to achieve excellence in research and make contribution to the engineering profession and to the community at large. He has earnt a distinguished reputation as a researcher of international standing acting as the editorial board member of discipline SCI journals, invited assessor for highly competitive research grants (e.g., ARC ITRP/DP/LP/LIEF and NISDRG), regular referee of world-top discipline journals, and invited seminar speaker at top universities.Ĭurrently, Dr Peng is the chief investigator along with A/Prof Elham Doroodchi and Prof Behdad Moghtaderi leading an ARC Discovery project, "Bubble dynamics in fine droplets: behaviour and control", and with Prof Moghtaderi leading several industry funded research projects mostly relating to mine safety, clean energy, and greenhouse gases abatement. His work had also delivered direct solutions to challenging problems in the industry such as effective mitigation strategies for various explosion scenarios in underground mines, detonation and flame arresting properties of reverse thermal oxidizer devices, optimisation of large-scale oil/water separators, identification of lower explosive limit in molybdenum plants, etc.ĭr Peng's recent research performance / achievements were recognised by the prestigious Excellence Award for Outstanding Research at UoN (2020). His research ranges from fundamental studies of physics, through applied investigation, to the development of new technologies using advanced experimental, numerical, and theoretical approaches.ĭr Peng's most significant contributions to the field have been a series of fundamental studies that have significantly deepened the understanding of the physics underlying multi-phase flow systems, especially complex physical/chemical interactions between particles, gas bubbles, liquid drops and fluid phases. Dr Peng has over 15 years of research experience in multi-phase flow and processes that involve solid particles, gas bubbles and liquid drops.
