A CFD- RSM study of cuttings transport in non-Newtonian drilling fluids: Impact of operational parameters
( Elsevier B.V. , 2022 , Article)Cuttings removal out of the wellbore represents a real barrier for successful drilling operations. The performance of hole cleaning is determined by several factors. The current article provides a theoretical study of the ... -
Axisymmetric Powell-Eyring fluid flow with convective boundary condition: optimal analysis
( Springer Netherlands , 2016 , Article)The effects of axisymmetric flow of a Powell-Eyring fluid over an impermeable radially stretching surface are presented. Characteristics of the heat transfer process are analyzed with a more realistic condition named the ... -
Dry sliding tribological properties of a hard anodized aa6082 aluminum alloy
( MDPI AG , 2020 , Article)The applications of aluminum and its alloys are still limited by low hardness and low wear resistance properties. Surface modifications, such anodizing and plasma electrolytic oxidation, represent a feasible way to overcome ... -
Effects of high frequency drive speed modulation on rotor with continuous stator contact
( Elsevier Ltd , 2017 , Article)In many mechanical systems, rotating structures experience continuous rotor-stator contact and torsion motions are dominant in the response. Drill strings used in the oil and gas industry represent one example of rotating ... -
Friction and wear response of a hard-anodized aa6082
( Trans Tech Publications Ltd , 2021 , Conference Paper)The properties of anodized aluminum, and wear resistance in particular, are of high interest for the scientific community. In this study, discs of AA6082 were subjected to a peculiar hard anodizing process leading to ... -
Modeling Asphalt Pavement Frictional Properties using Different Machine Learning Algorithms
( Qatar University Press , 2023 , Conference Paper)The objective of this work is to use some machine learning algorithms and test its efficiency in developing models to predict Locked Wheel Skid Trailer (LWST) values from Dynamic Friction Tester (DFT) and Circular Texture ... -
Quantifying morphology of sands using 3D imaging
( American Society of Civil Engineers (ASCE) , 2015 , Article)Particle morphology plays a significant role in influencing engineering behavior of granular materials. Surface texture, roundness, and sphericity represent distinct multiscale measures needed to fully describe particle ... -
Study on the effects of tool tile angle, offset and plunge depth on friction stir welding of poly(methyl methacrylate) T-joint
( SAGE Publications Ltd , 2019 , Article)The effects of tilt angle (TTA), plunge depth (TPD) and offset (TO) of tool in friction stir welding of poly(methyl methacrylate) T-joint were investigated. To understand better the effects of process parameter, thermomechanical ... -
The effect of sliding speed on the wear of steel-tool steel pairs
( Elsevier Ltd , 2016 , Article)This study examines the effect of sliding speed and surface temperature on the wear behavior of an unlubricated mild steel-tool steel contact pair using the pin-on-disc test. The operating conditions and contact pair are ... -
Tribological studies of nanomodified mineral based multi-grade engine oil
( Research India Publications , 2017 , Article)This research study investigates the tribological behaviour of mineral based multi grade engine oil reinforced with nanoadditives using a pin on disc tribometer under different frictional conditions. Load, sliding speed, ... -
Wear resistance investigation of titanium nitride-based coatings
( Elsevier Ltd. , 2015 , Article)The wear of components while they are in service is a predominant factor controlling the life of machine components. Metal parts are often damaged because of wear-driven failures causing the loss of dimensions and ...
