Overview

  • (1) Major Research Field


  • The major field of the Murakami and Kato Laboratories is environmental control engineering for building and urban technology based on both experimental techniques and numerical simulation methods. Methods for predicting and controlling physical properties such as air flow, heat and pollutant diffusion and lighting through urban regions, around building complexes, and within rooms are studied. Research topics ranging from urban scale to indoor scale are pursued by Professor Murakami, those ranging from building complex to indoor space are done by Associate Professor Kato and those ranging from national scale to building complex are done by Lecturer Mochida. Methods for controlling the physical environment of humans are studied from the view point of safety in disasters like fire and also from the view point of health and comfort in daily life. The studies consist of following sub fields.
    1) Measuring techniques of the physical environment of living spaces ranging from indoor to urban spaces;
    2) Assessing and evaluating the environment and establishing design criteria;
    3)Prediction methods using both experiments and numerical simulations of heat and flow fields for living spaces;
    4) Energy efficient methods for controlling human living spaces;
    5)Synthetic and totaled assessment of the environment of human living spaces.


  • (2) Recent Research Topics


  • In recent years, prediction methods using CFD (Computational Fluid Dynamics) based on mathematical models of turbulent flow have been developed. The distributions of physical properties such as heat and contaminant within the human environment are strongly affected by turbulent flow-fields.
    CFD technique is a very promising method for use in the building and urban technology and it fills the gap between experimental and theoretical methods. Precise model experiments also have been conducted to analyze the characteristics of heat, contaminant and airflow distributions and also to obtain data for validating the turbulent flow simulations. Using these data, prediction methods have been developed for the turbulent flow fields in and around buildings with complex geometry.
    The coupled simulation of flow, radiation, and conduction phenomena concerned with the building thermal environment has been also developed. The results of these analyses of the physical environments have been used for the practical designs of various new type buildings.
