A New Investigation of the Effect of Airfoils Thicknesses

Nov 30,2019·A New Investigation of the Effect of Airfoils Thicknesses on the Transition Point in Laminar Flows using XFOIL.Abstract In this work,a detailed analysis has been performed to study the influence of airfoil thickness on the location of the laminar to turbulent transition point.This study has been conducted on six types of airfoils that belong to the FFA_W3_XXX series [1].EFFECT OF MIG WELDING INPUT PROCESS PARAMETERSA ccording to Tsegelsky (29) reinforcement should usually be 20% of the plate thickness.Excessive reinforcement height does not improve the strength of the weld but in fact increases th electrode consumption.Due to sharp changes in plate thickness,stresses may concentrate at this point leading to failure of welded joints due to the notch effect.Effect of pulsed current on temperature distribution,weld bead profile,the microhardness,the residual stress distribution,the microstructure and the tensile properties of gas tungsten arc welded AA6351-T6 aluminium alloy joints.2 Experimental procedure In this investigation,plates with 4 mm in thickness were used as the base materials.The chemical

Exploring the fabrication limits of thin-wall structures

Aug 11,2020·The actual thickness of the single-bead wall is always slightly larger than the estimated wall thickness.The enlargement of thickness was expected as surrounding powder delayed the heat dissipation due to the lower thermal conductivity compared with that in bulk material.Image artifacts in digital breast tomosynthesis Image artifacts in digital breast tomosynthesis investigation of the effects of system geometry and reconstruction parameters using a linear system approach.Hu YH(1),Zhao B,Zhao W.Author information (1)Department of Radiology,State University of New York at Stony Brook,Health Sciences Center Stony Brook,New York 11794-8460,USA Influence of welding processes on weld bead geometryThe utmost important weld bead geometry parameters are depth of fusion,fusion width or bead width,bead height and HAZ area.These parameters are measured as shown in Fig-1.Imperfections in weld geometrical parameters will have intense effect on weld joint performance.It negatively affects the performance of the welded structure.
