Validation of Dishwasher CFD Model Using PIV
2011 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

The condensation drying phase during a dishwasher cycle can consume up to about 60 % of the total energy needed in the energy declaration program. A comparison between a static drying system with no fan and a dynamic drying system with a fan, to investigate if energy consumption for drying can be decreased, is very interesting. A Computational Fluid Dynamics (CFD) model has been set up in a first step to investigate dynamic drying with a fan. The aim of this master thesis project is to provide an experimental data set for validation of the CFD model and also to get a better understanding on how plate distance will affect the drying. The experiment was carried out at Luleå University of Technology using Particle Image Velocimetry (PIV). It is a laser method that does not disturb the measured flow. For two different air flow rates 20 m3/h and 30 m3/h the velocity distribution was measured between the dinner plates and around a cup in the corner. The results showed that the flow is going downward between the dinner plates. When comparing the PIV data with the CFD results the agreement was better further away from complicated geometries. Increasing the plate distance from 10 mm to 20 mm improves theoretical drying, but when increasing from 20 mm to 30 mm the drying stays the same.
