Air quality

Research centres around the world have developed different configurations to represent a computer simulated person. The manikins are very different with respect to size, form, heat emission details, turbulence models, etc. The variation may reflect the various possibilities in software and different standards for persons from country to country.

Two benchmark tests are introduced for the test of a CFD manikin, one for mixing ventilation and one for displacement ventilation. The idea behind the benchmark is to test the individual concept under the SAME boundary conditions. The tests of different manikins may improve the design of a CFD manikin and lead to standards.

Thermal comfort

Computer simulated persons in CFD environment have been developed during a number of years for the simulation air quality problems. It is foreseen that a new development of computer simulated persons will focus on thermal comfort problems. This benchmark test will therefore work with the heat loss from manikins with the aim to predict how humans will react to different climatic situations.

The thermal comfort benchmark test (manikin heat loss benchmark test) is based on thermal manikin measurements. It can be used as calibration of a virtual manikin positioned in a CFD simulated environment. The results are presented not only as whole body influence, but also with local information on how the climate varies over the human body.

Personalized ventilation

The use of personalized ventilation (PV) is a widely studied topic in the indoor environment community. There is a wide range of PV devices studied using experimental setups and computational fluid dynamics. The PV devices vary with respect to size, location, airflow, temperature, turbulence etc. A benchmark test is introduced for a single nozzle PV system directed toward the breathing zone of a computer simulated person in a displacement ventilation system. The benchmark is designed to test individual variation (grid development, detail of manikin, software model etc.) using the boundary conditions proposed.
