Urban computational fluid dynamics simulations set-up validations

Computational Fluid Dynamics (CFD) simulations for residential areas are becoming increasingly important as the urban population keeps growing and extreme weather conditions due to climate change are becoming more prevalent. Since CFD simulations simulate and visualise fluid flows, users can analyse and predict air flows in urban environments,...

CFD Modelling of HIsarna Off-gas System

HIsarna is a new and breakthrough smelting reduction technology for producing liquid hot metal for steelmaking directly from iron ores. Compared to the conventional blast furnace route, HIsarna achieves a 20% reduction in CO2 emissions by eliminating coking and the need for iron ore agglomeration processes such as sintering and pelletizing and...

The wind-induced dynamic load on high-rise structures by the use of CFD

During the last decades, the development of high-rise increased quickly. The Eurocode is frequently used to make wind calculations for high-rise structures. To make those calculations, the dynamic wind load is simplified to a conservative equivalent static load. An alternative to calculate wind loads is a physical wind tunnel test. Wind tunnel...
