A tribute to Yoichiro Matsumoto on the occasion of his 60th birthday
This special issue is dedicated to Yoichiro Matsumoto on the occasion of his 60th birthday. A six-session symposium on Advances in Computational Fluid Mechanics and Fluid–Structure Interactions was organized to celebrate this occasion at the ASME International Mechanical Engineering Congress, which was held in November 2009, in Lake Buena Vista, Florida. This special issue contains papers authored by friends, collaborators, and former students of Yoichiro Matsumoto who gave presentations at this symposium.
Yoichiro Matsumoto contributed much to computational and experimental fluid mechanics, mentored many young researchers in Japan, and has been a dedicated participant in research gatherings on computational fluid mechanics and fluid–structure interactions (FSI). This special issue is another occasion to recognize his accomplishments and thank him for his contributions.
Yoichiro Matsumoto received his BS, MS, and PhD degrees in Mechanical Engineering from the University of Tokyo, and has been serving on the faculty there since then. He made significant research contributions to multiscale phenomena in fluid mechanics, dispersed multiphase flows, bubbly liquids, molecular dynamics, and medical applications of ultrasound with microbubbles. He received the Calvin Rice Lecture Award from the ASME in 2005, and was selected for the ASME Applied Mechanics Division Ted Belytschko Applied Mechanics Award, which will formally be given in November 2010.
This special issue contains several papers on FSI modeling, with a wide range of applications. The applications include patient-specific modeling of cerebral aneurysms, blood flow, performance analysis of Orion spacecraft parachutes, modeling of parachute clusters, and aerodynamic and FSI modeling of wind turbine rotors at full scale. Both the moving-grid techniques (such as the arbitrary Lagrangian–Eulerian and space–time methods) and fixed-grid techniques are used in dealing with the moving interfaces. The coupling techniques used include the direct and block-iterative methods.
A good number of papers focus on numerical method development, performance evaluation, and conceptual framework. These include the stabilized formulations for combustion, modal analysis for 3D sloshing with surface tension, nested and parallel sparse algorithms, multidimensional kinetic approach for rarefied and transitional flows, ultrasound simulation techniques, investigation of the Navier–Stokes and Lattice–Boltzmann approaches on octree-like grids, a family of residual-based stabilized methods for Stokes flows, and a heterogeneous multiscale modeling framework for hierarchical systems of partial differential equations.
We would like to thank the authors for the effort in preparing their contributions and for meeting the deadlines.
