Numerical Investigation of the Unsteady Thermal Plume around Human Body in Closed Space

摘要

The unsteady numerical simulation was conducted to investigate the unsteady thermal plume around human body in closed space,with a relative high resolution of grid and time step.The instantaneous flow filed evolution process was successfully analyzed in detail by simulation approach.A set of time-average statistics of the velocity and the temperature of thermal plume around body were obtained,as well as the fluctuation velocity,the fluctuation temperature and other unsteady characteristics.
