This paper deals with the integration of CFD analysis tool with genetic algorithms. This integrated process presents advantages in generating design alternatives that tally with multiple design, thermal and ventilation criteria.

Model experiments were conducted to know the airflow in a room equipped with a ceiling multi-cone diffuser A comparison between the results of CFD and the model experiments has been done.

The main objective of this paper is to describe methods for characterising air diffusers for CFD simulation of the room airflows. As a basis of work, a circular diffuser was used for working out and testing those methods.

In this paper the application of CFD simulation with unstructured fine elements system was carried out to obtain airflow data for the boundary conditions for an air flow.Tthe results were compared with the measured data.

Part 1 of this paper gives first an outline of the experiment (full-scale measurement of the air velocity carried under isothermal condition), then discusses the 2 modeling methods - the BOX method and the P.V. method - used for CFD simulation.The results of calculations with the 2 methods showed good agreement with the experimental data.

This method enables the determination of the influence of heating source characteristics on mean radiant temperature for composite room surfaces, as well as on thermal comfort and discomfort. A maximal possible thermal comfort area can be achieved with the determination of the best interactive influence between the building structure and its heating system.

The paper deals with the CFD analysis performed for a family house residence, which is in the design phase : the aim was to test several concepts for heating ( floor heating, floor convectors, both systems) in terms of thermal comfort.

The objective of this parametric study is to vary some parameters related to the conception of an atrium in order to analyse through CFD calculations their impact on the thermal behaviour during the critical summer conditions. The guideline produced are intended to help the architects especially at the first stage of the conception process.

This paper deals with an approach to a multizone airflow analysis that can account for mechanical energy conservation. It is shown that the resistance (dissipation) provided by zones in a multizone analysis should not be ignored.

The results of a study testing the possibility of using Dynamical Thermal Modelling (DTM) techniques within CFD are reported in this paper. Two test procedures (an extensive one and a simplified one) were conducted for the modelling of an enclosure, to model heat exchanges through building materials and effects on internal temperatures and air flows.
