ABSTRACT: This paper presents a general equation for shear stress in turbulent flow over smooth surfaces at Reynolds numbers ranging from 2 × 103 to 6.5 × 105 (based on the boundary layer thickness ...

This paper presents a general equation for shear stress in turbulent flow over smooth surfaces at Reynolds numbers ranging from 2 × 10 3 to 6.5 × 10 5 (based on the boundary layer thickness and the ...

In this video we explore bending and shear stresses in beams. A bending moment is the resultant of bending stresses, which are normal stresses acting perpendicular to the beam cross-section. We can ...

Abstract: Insights into stress-dependent reflection and transmission (R/T) of elastic waves are crucial for geophysical applications involving stress-dependent and angle-dependent seismic data. Stress ...

It has been shown that right ventricle (RV) hypertrophy involves significant compensatory vascular growth and remodeling. The objective of the present study was to determine the functional ...

Laboratory experiments designed to deform ice at its pressure-melting temperature were like grabbing a bagel at the top and the bottom, then twisting the two halves to smear the cream cheese in the ...

AMES, Iowa – Neal Iverson started with two lessons in ice physics when asked to describe a research paper about glacier ice flow that has just been published by the journal Science. First, said the ...

This polarized light image shows ice grains deformed in experiments with the ring-shear device in Neal Iverson's Iowa State laboratory. The experiments show that grains, on average, grow about 3 times ...

This study investigates countercurrent air-water two-phase flow in vertical pipes with inner diameters of 26 mm and 44 mm and a height of 2000 mm, under controlled conditions to eliminate heat and ...
