On the accuracy of CFD simulations of cross-ventilation flows for a generic isolated building: Comparison of RANS, LES and experiments

open access: yes, 2017
Accurate and reliable computational fluid dynamics (CFD) simulations are essential for the assessment of cross-ventilation of buildings. To determine which CFD models are most suitable, validation studies are required. A detailed review of the literature

Buoyant flows in street canyons: Comparison of RANS and LES at reduced and full scales

open access: yesBuilding and Environment, 2018
Reduced-scale experiments and full-scale field measurements show contradictory buoyancy effects from heated windward walls. Reduced-scale experiments exhibit significant thermal effects, but full-scale field measurements show a negligible thermal effect ...

Study on effects of wall mass transfer condition for measurement of geometry factor

open access: yesNihon Kikai Gakkai ronbunshu, 2016
It is necessary to evaluate the geometry factor for predicting the flow accelerated corrosion (FAC) in the plant piping. Geometry factor is defined as the ratio of the wall mass transfer coefficient in the piping systems (such as orifices, elbows) to ...
