Objectives

This proposed BIRS workshop will focus on several important topics that have fundamental scientific merits and significant engineering application values. Energy, environment, chemical processing, nanotechnology and information modelling and simulation require the collaborative efforts of a diverse group to maximize the outcomes, including basic science from scientists, technical expertise from engineers, modelling and numerical skills of mathematicians and the modern techniques of computer scientists. The simulation and modelling work is challenged by numerical solutions to coupled systems of nonlinear, multiscale and time-dependent partial differential equations (PDEs). There are multiple temporal and spatial scales and nonlinear effects presented and large scale and long time simulation required. The proposed workshop will promote, enhance and stimulate cross-continental research interactions and collaborations in mathematics, science, and engineering impacting the modeling and simulation field by bringing many minds together for unique and meaning solutions.



The first objective of this workshop is to bring together world-class active researchers in science and engineering modelling and simulation. Discussions will address past, recent and upcoming practical applications of prospective advances. The speakers will summarize important advances from the past five years and share their knowledge of the current problems, state-of-the-art novel techniques, and ideas to address major challenges. The breadth of challenges will engage all the participants to consider how their niche knowledge can be used to advance the work of each participant. This becomes an excellent vehicle to the development of new techniques and creative solutions for modelling and simulation challenges. The intent is to invite junior researchers as well. They need to be mentored and connected to the leaders of the fields, building strong relationships. The unique perspectives and the outcomes of their research and application will set the directions in the new century.



A second objective is to utilize this workshop as a platform to establish an Association of Chinese Professors in Canada. China is Canada’s second largest trading partner, a relationship that continues to grow, tripling since 2003. The establishment of such Association will enhance the bilateral relationship between Canada and China in education, research, culture and economy.



Some of the Workshop themes include:



A. Multiphase Fluid Flow and Transport



Energy and environmental modelling has diverse fluid flow and transport problems. These problems involve coupled systems of nonlinear, time-dependent partial differential equations that are often degenerate. The focus of this area will be on the origin and derivation of their models, the analysis of their nonlinear effects and consequences for real applications.



B. Interfacial Phenomena in Mineral and Material Processing



Effective processing of Alberta oil sands to extract bitumen will secure Canadian energy sources for the next 200 years and flotation shows great promise for primary separation. In flotation, various colloidal interactions determine the success and efficiency of separation. It is essential to understand these interactions. Their study involves measuring the forces between various phases directly with the atomic force microscope, complemented by a contact angle and zeta potential measurements. Their fundamental knowledge will be used to understand the problems encountered in the existing oil extraction processes and to develop a more versatile, effective process.



C. Spatially Explicit Carbon and Water Cycle Modelling



Various inverse modelling techniques are currently available for estimating regional carbon fluxes using atmospheric CO2 concentration observations. However, the number of currently available observation stations is still sparse relative to the size of the global surface and this limits the number of regions that can be reliably inverted globally without using additional information as constraints to the inversion. New inverse modelling and simulation techniques must be developed for estimating carbon fluxes over more regions globally and with finer grids of these regions.



D. Air Pollution and Industrial Wastes



In the air pollution area, the workshop emphasis is on pollution prevention through emission abatement and the fate and transport of hazardous air pollutants (HAPs) in the lower troposphere. Reaction kinetics of multi-phase systems need to be studied and efficient sulphur-producing flue gas desulphurization (FGD) technologies need to be developed. Natural processes at various scales from the sorption of acidic gases onto the surface of ice crystals to the below-cloud snow scavenging of gaseous and aerosol-associated HAPs need to be studied. A better understanding of the underlying chemistry and physics in these natural processes through modelling and simulation will lead to a greater confidence in the identification of the environmental pathways of pollutants and quantifying their effects on air quality and climate change.



E. Nonlinear Effects on Propagation Properties of Numerical Models



The propagation properties, such as stability, amplitude and phase portraits of nonlinear flow and transport processes are not easily determined. Convergence of numerical algorithms utilized in modelling and simulation of these processes is not easily shown. A fully nonlinear analysis is limited to specific forcing terms and initial conditions. Current approaches employed in the treatment of nonlinear effects on the propagation properties of numerical models of flow and transport processes and operator splitting solution schemes will be discussed.



In addition to the regular workshop presentations, there will be also considerable time for interactions between participants (a tentative list of individuals invited to participate is included). The workshop organizers will coordinate round-table sessions where questions and answers can be shared. Due to the high-level and interdisciplinary nature of the participants invited, those who attend this proposed workshop will be exposed to novel ideas and build new relationships for future collaborations. The workshop presentations, discussion at the round-table sessions and possible future collaborations among the participants will support significant progress of mathematics, science and engineering modelling and simulation.



The workshop organizers believe in equality and will ensure that youth and women, often underrepresented in these events, are invited to attend.



A list of potential speakers is included. An invitation has been sent to every proposed speaker in this list, and 80% of them have indicated their intent to participate in the workshop. The speakers are chosen to explore a range of modeling and simulation techniques for phenomena arising from mathematics, science and engineering. Clearly, some of the proposed speakers including Xiaoyi Bao, Jingming Chen, Ming Li, Weihong Song, Ke Wu, Zhenghe Xu, En-hui Yang, and Jesse Zhu are world-renowned and prominent scientists and engineers; they are all Fellows of Royal Society of Canada and their participation will bring a lot of appeal to the proposed workshop. We look forward to them sharing their perspectives on newest developments in modeling and simulation.
