The examination and estimation of unsteady ow phenomena around moving vehicle or machines are crucial for the realization of high-performance vehicles and machines. In our group, a new type of numerical simulation scheme has been developed and the technology has been applied to various engineering fields including solar cars, solar airplanes, pumps, wind turbines, ships, medical simulation, and so on. Furthermore, our group has carried out many collaboration works with various industrial companies or other universities and research institutes. The technology has also contributed to great results of the Tokai University Solar Car Team in some world solar car challenges.ResearchAreasEngineeringKeywords■Unsteady Aerodynamics■Flow Simulation■Vehicle Aerodynamics■Vortex Dynamics■AeroacousticsRelatedresearchSDGNumerical Simulation of Unsteady Flow Phenomena and its Engineering ApplicationAssociate ProfessorKota FukudaUndergraduate School of EngineeringDepartment of Aeronautics and Astronautics - Aerospace courseUndergraduate School of EngineeringDepartment of Aeronautics and Astronautics - Aerospace courseManagement of brain’s physiological conditions involving intracranial pressure, cerebral blood flow, cerebral temperature, and cerebral metabolism in the intensive care unit is extremely important in resuscitation therapy including cerebral hypothermia. Automating these controls will not only improve treatment eect but also reduce burden on the medical sta and suppress medical cost. Therefore, in our laboratory, an automatic control system of intracranial pressure, cerebral blood flow, brain temperature, and cerebral metabolism is being developed, by establishing control algorithm, measurement method, and operation method. Additionally, a decision-making model including learning function is also being constructed for simply analyzing and classifying personal characteristics based on the PID structure. This model can streamline the operation of organizations and groups and facilitate maximizing personal compatibility.ResearchAreasComplex systemsKeywords■Automatic control system■Physiological condition model■System development■Brain resuscitation■Therapeutic hypothermiaRelatedresearchSDGDevelopment of an automatic control system of brain's physiological conditions for brain resuscitation treatment.

The shock wave does appear around high-speed transports, launch rockets, and space capsules including planet probing. Therefore, detail understanding and precise prediction of behavior of shock waves is significantly important for safe operation of aero/space crafts. Furthermore, to understand the eects by shock waves is important for safety of dairy life because the shock wave is generated by sudden energy release in the air, such as explosions and lightning. At this laboratory, the research projects on unsteady shock waves oscillation around aero/space crafts, the advanced propulsion device using detonation, and explosion safety have been progressing.
