Numerical Simulation of Non-normal Wind Load on Porous Fences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)
This paper presents a numerical simulation of non-normal wind loads on a porous fence. It was found that non-normal wind load has significant impact on the performance of the fence in terms. The performance of the fence was measured as the effective fence zone behind the fence where flow characteristics and normal drag coefficients were maintained within safe level. It is recommended the incidental ...
Thaw Penetration in Frozen Ground Subjected to Hydronic Heating
(Peer reviewed, 2016-09-22)
To facilitate excavation and foundation work in seasonally freezing or permafrost regions, the frozen soil must be thawed, either by natural (solar) thawing, or by artificial thawing where an auxiliary heat source is utilized to accelerate the process. In this paper, the process of rapid thawing of frozen ground subject to hydronic heating is studied. In particular, the performance characteristics ...
Control of Airborne Noise Generated in the Cavities of a T-Slotted Aluminum Cylindrical Column
(Peer reviewed; Chapter, 2018-06-11)
This paper presents a study of airborne noise generated by a T-slotted cylindrical aluminum hollow column with six slots of the type used for the construction of communication towers. Noise is a very distracting phenomena and an environmental concern caused by various sources. Noise pollution is becoming more severe with the introduction of massive human activities and the use of heavy machineries, ...
