Prof. Bin Teng, Dalian University of Technology, China
Prof. Teng Bin (1958-), born in Dalian. He graduated from Dalian University of Technology and received his doctorate in 1989. He did his post-doctoral research in Oxford from December 1990 to January 1993. He was a specially appointed professor of Dalian University of Technology under the "Cheung Kong Scholars Programme" by Ministry of Education from 2001 to 2005. He engaged in the work of interaction of waves and coastal and offshore engineering structure. He also had an intensive study on the interaction of nonlinear waves with deep-sea structures and dynamic response of marine structures. He proposed new integral equation for the wave diffraction and radiation, a fast algorithm for the second-order velocity potential on the infinite free surface, and apply this algorithm to calculate the third-order wave force on axial symmetric bodies. He set up a two-terms expansion method for simulation of the large amplitude drift motion of deep water moored platforms. He developed a frequency-domain and a time-domain software packages for computing the nonlinear wave loads on offshore structures and nonlinear dynamic response of ocean engineering structures. Prof. Teng is a winner of a National Outstanding Youth project and the principal investigator of one key project and a number of normal projects funded by National Natural Science Foundation. He published more than 300 papers in the domestic and oversea journals. He was awarded the second and third class National Science and Technology Progress Award, respectively.
Speech Title---Potential Methods for Wave Loads on Marine Structures
Abstract-Potential theory is widely used for compute wave loads on large sized structures as its lower cost comparing with the viscous models. Fully nonlinear model can be set up based on the nonlinear free surface and body surface conditions on the exact free surface and body surface. The free surface and body surfaces are simulated with the computation by a time marching method. In practical application the direct simulation with the fully nonlinearity model is a great challengeable with the increase of structure scale and the wave nonlinearity. Thus, simplification must be applied to develop more efficient and steady models. The state of the art includes: the fully nonlinear model, perturbation model, large amplitude model, body exact model, weakly diffraction model, shallow water model and Cummins model. In this talk, the development of the models and their applications will be introduced.

Speech Title---Meshless Method for Violent Wave-Fluid-Structure Interaction
Abstract-When encountering extreme wave, the
structure may produce elastic vibration and considerable
deformation. In this presentation, an in-house
MPSFEM-SJTU solver based on the fully Lagrangian MPS-FEM
coupled method is proposed to solve the fluid-structure
interaction problems. The coupling MPS-FEM is extended
to a 3-D FSI problems. In fluid-structure interface, the
condition of displacement and force equivalence can be
met. The interaction between rigid-body and elastic
deformation is considered in present work. Interaction
between breaking-dam and moored flexible platform is
numerically studied and present results show good
agreements with previous published data. The slamming of
a floating ship hull is simulated to show the capability
of the coupling method in capturing large free
surface/structure displacement.
The proposed MPS-FEM coupled solver is powerful for
problems of structural deformation induced by violent
free surface flow.

Speech Title---Application of Biosurfactants for Oil Spill Remediation
Abstract-An evaluation of the management options must be made for contaminated sites. In particular, various techniques must be considered for the remediation of water and sediments when the release of hazardous materials becomes a serious problem. The options can include physical, biological, and/or chemical treatments. Sustainable management options for contaminated sites are required and will be evaluated. Selection of the most appropriate remediation technology must coincide with the environmental characteristics of the site and the ongoing fate and transport processes. To be sustainable, the risk to human health and the environment at the site must be reduced, and not be transferred to another site. Cost-effectiveness and sustainable solutions are significant factors in determining the treatment. The application of biosurfactants has been evaluated as alternatives to chemical reagents due to their surface active and emulsifying properties, low toxicity, biodegradability, unlimited applicability and relative low production cost for sustainable remediation. Studies showed that for effective application of biosurfactants, they should be selected based on pollutant characteristics and properties, treatment capacity, costs, regulatory requirements, and time constraints. Moreover, understanding of the mechanisms of interaction between biosurfactants and hydrocarbon contaminants or the contaminated environment can assist in selection of the appropriate biosurfactants for sustainable remediation. This presentation will include research on various environmental applications of biosurfactants, particularly for hydrocarbon remediation.
