Special Issue on “Machining Dynamics and Parameters Process Optimization”
(MDPI, 2020-12-14)
In 1907, F.W Taylor—the father of production engineering—exposed the fundamentals of modern machining and defined chatter as the most obscure and delicate of all problems facing the machinist [...]
Uncharted Stable Peninsula for Multivariable Milling Tools by High-Order Homotopy Perturbation Method
(MDPI, 2020-11-06)
In this work, a new method for solving a delay differential equation (DDE) with multiple delays is presented by using second- and third-order polynomials to approximate the delayed terms using the enhanced homotopy ...
Estimation of the Heat Loss Coefficient of Two Occupied Residential Buildings through an Average Method
(MDPI, 2020-11-02)
The existing performance gap between the design and the real energy consumption of a building could have three main origins: the occupants’ behaviour, the performance of the energy systems and the performance of the building ...
Analysis of the dressing process using stationary dressing tools
(Elsevier, 2017)
Grinding process is a very important process in machining industry to manufacture high quality part. The correct preparation of grinding wheel involves dressing process taking importance to optimize grinding process. Due ...
Machining Stresses and Initial Geometry on Bulk Residual Stresses Characterization by On-Machine Layer Removal
(MDPI, 2020-03-22)
Prediction and control of machining distortion is a primary concern when manufacturing monolithic components due to the high scrap and rework costs involved. Bulk residual stresses, which vary from blank to blank, are a ...
A reliable turning process by the early use of a deep simulation model at several manufacturing stages
(MDPI, 2017-05-02)
The future of machine tools will be dominated by highly flexible and interconnected systems, in order to achieve the required productivity, accuracy, and reliability. Nowadays, distortion and vibration problems are easily ...
Five MegawattWind Turbine Power Output Improvements by Passive Flow Control Devices
(MDPI, 2017-06)
The effects of two types of flow control devices, vortex generators (VGs) and Gurney flaps (GFs), on the power output performance of a multi-megawatt horizontal axis wind turbine is presented. To that end, an improved blade ...
Microtab design and implementation on a 5MW wind turbine
(MDPI, 2017-05-24)
Microtabs (MT) consist of a small tab placed on the airfoil surface close to the trailing edge and perpendicular to the surface. A study to find the optimal position to improve airfoil aerodynamic performance is presented. ...
Gurney Flap Implementation on a DU91W250 Airfoil
(MDPI, 2018-11-06)
Abstract
The increasing capability of Wind Turbine (WT) based power generation systems has derived in an increment of the WT rotor diameter, i.e., longer rotor blades. This results in an increase of the electrical power ...
On the influence of conformity on wheel–rail rolling contact mechanics
(Elsevier, 2016-07)
The aim of this work is to assess the effects of conformity on local contact related quantities at the wheel–rail interface such as traction distributions, subsurface stresses and frictional work distributions.
For this ...
