Abstract: This paper deals with a numerical investigation on natural convection heat transfer in a long horizontal annular region formed with a heated inner cylinder and a cooled outer cylinder. Identifying ...

Abstract: Demand for underground pipelines and the rehabilitation of existing utility infrastructure has been increasing due to urban expansion, continuous development, and the deterioration of existing buried assets. Often, ...

Abstract: Expansions in concrete dams may be caused by chemical or physical sources; however, in certain occasions the evidences observed in the dam may not be attributed to a single cause. Mequinenza is an example of a concrete dam ...

Abstract: This paper describes scale-model laboratory experiments with salt-bath simulations, on the flow and stratification in two coupled rooms connected to the exterior by a single vent. The two rooms ...

Abstract: This paper introduces a new shear reinforcement beam-column joint mechanism—the twisted opposing rectangular spiral—and carries out numerical and experimental investigates. Converting the conventional discontinuous shear ...

Abstract: An analysis of the flow that depends on the fuel composition (natural gas) in the combustor–transition piece system, applying computational fluid dynamics, is presented. The study defines the ...
