Koja gains scientific knowledge
Koja's Test Engineer Petteri Sippola has done research on the effects of triboelectric charging on gas-particle flows at the Tampere University of Technology before his entry to Koja. The research article "Experimental and numerical study of wall layer development in a tribocharged fluidized bed" has been published in the Journal of Fluid Mechanics (Jufo2) in June 2018.
The article handles the effects of electrostatic forces induced by tribelectric charging in an experimental fluidized bed. In general, triboelectricity can cause undesirable agglomeration and adhesion of granular materials in industrial processes or even an explosive hazard in flammable environments. The aim of the research is to develop a method to simulate the effects of triboelectric charging in various situations. Read the article in the Journal of the Fluid Mechanics »
Sippola’s research supports the ongoing study on the fouling process simulation of a fin-and-tube heat exchanger, which is a part of the PhD thesis by Koja’s R&D Engineer and PhD Student Turo Välikangas. The results from this project will be utilised in Koja’s research and development in the future.
During the last few years Koja has significantly invested in the research and development as well as testing. Sippola, who started working at Koja in the beginning of 2018, works at Koja's new R&D Center:
"As a test engineer I get to utilize my full potential which has developed in my previous studies and research. It's great to be a part of the unique R&D center, right from the start."
