Towards a virtual climate chamber – A physical experimental study

University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

Abstract: This project focuses on experimentally characterizing one of the tools used at Ericsson AB to test product performance, the climatic chamber. By conducting experiments inside the climate chamber and post processing the data obtained, the airflow inside it can be understood and compared to outdoor experimental data. One of the main sections of this work is to prove the hypothesis: The energy potential of the wind outdoors is greater than indoors, which is shown to be true when comparing values for the integral length scales of the flow, at the same mean wind speed. The second main part of this project is to obtain valuable experimental input that will serve to construct a virtual model of the climate chamber. With the conclusions drawn from the experiments, which involve heat transfer, boundary conditions for the numerical model can be established.
