Experimental Investigation of the Spread of Airborne CFU in a Research-OR under Different Air Flow Regimes using Tracer Particles
Schumann, Lukas; Hartmann, Anne; Hofer, Valeria; Kriegel, Martin (SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Aim of this experimental study is to compare different types of ventilation in operating rooms (OR) regarding the highest possible patient protection against airborne germs based on particle counting. Tracer particles with ... -
Is the air change efficiency sufficient to assess the removal of airborne contamination in mixing ventilation?
Brockmann, Gerrid; Hartmann, Anne; Kriegel, Martin (SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)This investigation analyze the correlation between two common methods to assess the ventilation effectiveness: An averaged contamination removal effectiveness (CRE) value based on the residual lifetime and the air change ... -
Limitations in the application of computer simulations of temperature rise of completely new designs of MV metal enclosed switchgear
Fjeld, Elin; Pedersen, Per Atle; Kriegel, Martin; Singh, Shailendra; Barrio, Sergio; Snajdr, Jaroslav; Li, ZuHui (Peer reviewed; Journal article, 2020)Temperature rise simulation deals with different physical domains describing heat generation and heat dissipation effects. Cigr working group A3.36 has conducted a study on temperature rise simulation of switchgear for ...
