An Integral Criterion for Turbulence Suppression in Swirling Flows

19.01.2018 | Ehsan Zaman, Ali Vakil, Mark Martinez, James Olson, The Canadian Journal of Chemical Engineering, 2018

ABSTRACT A numerical study of flow in rotating pipes was conducted to elucidate the relative importance of convection and turbulence. CFD (Computational Fluid Dynamics) simulations of flow inside a rotating pipe (D = 2 cm and L/D = 20) were carried out, using the Reynolds Stress Model, for ...

Study on Pyrolysis of Oil Sludge with Microalgae Residue Additive

17.01.2018 | Zhiqiang Gong, Zhentong Wang, Zhenbo Wang, Aixun Du, Peiwen Fang, Zhiqian Sun, Xiaoyu Li, The Canadian Journal of Chemical Engineering, 2018

ABSTRACT The pyrolysis of oil sludge (OS) with microalgae residue (MR) additive was conducted with a TGA and a tube furnace. The pyrolysis process of OS with the MR additive can be divided into three stages: 1) water evaporation, 2) the release of light groups of hydrocarbon compounds, the ...

Gaseous Ozone Decomposition over High Silica Zeolitic Frameworks

17.01.2018 | Nicolas Brodu, Marie‐Hélène Manero, Caroline Andriantsiferana, Jean‐Stéphane Pic, Héctor Valdés, The Canadian Journal of Chemical Engineering, 2018

Abstract For several decades, it has been known that ozone emissions are harmful to humans, plants, and animals. Heterogeneous catalytic decomposition is an efficient process for removing ozone from air. This study examines the effect of the zeolite's framework and pore width on efficiency ...

Role of Mineral Flotation Technology in Improving Bitumen Extraction from Mined Athabasca Oil Sands: I. Flotation Chemistry of Water‐Based Oil Sand Extraction

16.01.2018 | Joe Zhou, Haihong Li, Liyan Zhao, Ross Chow, The Canadian Journal of Chemical Engineering, 2018

ABSTRACT The role of surface hydrophobicity in water‐based oil sand extraction is examined from the perspective of mineral flotation separation. Although anionic carboxylates (sulphonates) released from bitumen are helpful for charging bitumen and liberating bitumen from sand grains, their ...

CFD Simulation of Hydrodynamics Characteristics in a Tank Stirred by a Hollow Self‐Inducing Impeller

13.01.2018 | Liangchao Li, Ning Chen, Kefeng Xiang, Beiping Xiang, The Canadian Journal of Chemical Engineering, 2018

ABSTRACT Hollow self‐inducing impellers are often used in gas‐liquid stirred tanks in many industrial processes. To understand the hydrodynamics characteristics of this type of stirred tank under aerated and unaerated conditions, a computational fluid dynamics (CFD) simulation study was ...
