Estimation of Indoor and Urban Thermal Environment by Using Computational Fluid Dynamics

Fluid dynamics is a field of study that involves investigating the behavior of fluids, including gases and liquids such as air, water, and oil. The field incorporates the area of computational fluid dynamics (CFD), which involves investigating fluids using computer simulations. In my research, CFD is applied to estimating indoor or urban thermal environment aspects, such as flow and temperature field, with the aim of designing air-conditioner or building configurations.


Assimilation of Numerical Models and Observation Data

Numerical models allow us to estimate indoor or urban thermal environments. However, to accurately predict future thermal environments, it is important to understand the current environment. In weather prediction, for example, numerous observed data from meteorological satellites and meteorological observation stations are used to reproduce current meteorological conditions, which are used to predict future weather conditions. This technique of combining observed data and numerical models is known as data assimilation. In my research, data assimilation methods are used to estimate indoor or urban thermal environments.
