Keynote's Title: Ultrasonically Catalyzed Gas Sensor Systems

Keynote's Abstract: High-performance gas sensing systems have huge potential applications in human health diagnoses, food industry, environmental safety, internet of things, chamber air quality monitoring, etc., due to the merits such as point-of-care testing, easiness to operate, simple and light structure, low cost, etc. My research group proposed the ultrasonically catalyzed gas sensing method in 2017, and then successfully applied the method into high-performance gas sensing and single-sensor E-noses. This lecture gives the detailed research results in this respect. The first part of this lecture includes principle of the ultrasonic catalysis in gas sensing, and structure and characteristics of the gas sensors catalyzed by gas borne ultrasound. In the second part, working principle and algorithms of ultrasonically catalyzed single-sensor e-noses, are given and explained, as well as the structure, system design and gas discrimination performance. The algorithms applied in the E-noses include the k-method, R-C method and machining learning methods. It shows that the ultrasonically catalyzed gas sensors have much better sensitivity and lower detection limit than the conventional ones, and ultrasonically catalyzed single-sensor E-noses have strong capability of gas discrimination and concentration measurement.

Keynote's Title: Cybersecurity in Global Aviation

Keynote's Abstract: Aviation nowadays is changing with the possibilities of the IoT and how Operation Technology offers real time solutions. What has not advanced as fast is the cybersecurity to protect as a critical infrastructure. The research will discuss what are the problems and risks and report on the conclusions of several research topics and what is now needing to be research. It argues that research to the solutions is limited by economies, technology and this is likely to become more of a problem as aviation advances. Furthermore, the risk added now the industry tackles the resistance from sustainability.

Keynote's Title: Mass conservation limitations in overset CFD with unsteady moving grids

Keynote's Abstract: Overset grid techniques (also known as Chimera grids, composite grids, or overlapping grids) were first introduced in 1966, and underwent significant exploration, particularly at NASA in the 1980’s and 1990’s. Commercial CFD codes, such as ANSYS Fluent, and STAR-CCM+, began supporting overset grids around 2015, significantly increasing the number of CFD practitioners utilizing this technique. 

An overset grid simulation consists of a background mesh and one, or more, body meshes that overlay the background. Cells in the background mesh are removed from the simulation and designated as hole cells if they cover the same geometric space as the body mesh. The cells near the edge of the removed region must overlap the edge of the edge of the body mesh. An interpolation stencil is developed for each cell in the background and body mesh in the overlapping region to exchange information throught the simulation. If the body mesh is moving, then the hole cell identification, and fringe-donor interpolation stencils must be updated each time-step.   

During the NASA years, overset methods were primarily applied to compressible flow simulations of multi-body external aerodynamics. In the early 2010’s, overset methods were adopted for incompressible underwater and naval surface ship simulations. The use of moving overset grids in incompressible flow simulations poses a unique challenge--how to account for the instantaneous mass conservation imbalance when the grid volume changes. If the body mesh moves by a small amount, relative to the size of the overlapping grid cells, then the fringe-donor interpolation stencils can simply be updated based on the new cell positions. However, if the mesh motion requires current hole cells to be reactivated, or new hole cells removed from the simulation, the total fluid volume continued within all active grid cells changes instantaneously. In an incompressible flow simulations, the instantaneous volume change results in a significant pressure oscillation, due to the pressure-mass coupl

Keynote's Title: Thermo-Mechanical Fracture Study and its Applications in nonhomogenous materials

Keynote's Abstract: The applications of nonhomogeneous materials are more and more widely in airplane, spacecraft and other astronautic equipment. Although nonhomogeneous materials, such as Functionally Graded Materials(FGM), and three-dimensional braided composites, have many advantages, the complex structure may arouse new difficulties in dealing with the crack problem, especially when the materials under thermo-mechanical loading. How to obtain the thermal fracture parameters in the material with complex interfaces effectively is a key problem for evaluating the astronautic equipment life and aircraft design. A modified interaction energy integral method (IEIM) combined with the extended finite element method (XFEM) is developed to deal with the thermal fracture problems of nonhomogeneous materials. This method can be proved to be domain-independent when the integral domain contains complex interfaces, so the application ranges can be enlarged greatly. Thermal fracture parameters, such as thermal stress intensity factors (TSIFS) and T-T-stress, are analyzed in thermal interface crack problems, heat flow problems, and thermal shock problems. Some structural integrity analysis examples in astronautics equipment are discussed using the present method. The results can be used to optimize and improve the design of astronautic equipment.
