This study investigates the effect of nonlinear strengths sloshing on damping performance side-mounted perforated baffles and discusses influence resonance characteristics flow. The model score is adopted to evaluate strength water sloshing. A microscopic a volume-averaged macroscopic are established simulate flow in two-dimensional (2D) tank with baffles. In addition, series experimental tests...

Influence of a vent hood at the exit of exhaust flue gas and flue baffles in the firetube on the temperature and flow fields of a gas tank water heater, as well as thestructure and amount of heat transferred to the water tank has been studiednumerically using two-dimensional steady state finite element simulation.Observations show that without a vent hood, there is a downward gas flow in theflu...

The system of steel shear wall is an initiative resistance system against the lateral load such as an earthquake and the wind that has been researched in the last three decades. Currently, this system is noticed more than other systems because of adequate stiffness, ductility, and more energy absorption. The system of steel shear wall with corrugated sheets has been offered as an innovative sys...

Flow in a circular pipe fitted with segmental baffles may be treated as a shellwithout-tube system. Its pressure drop has been calculated by adapting the Kern correlation [1] for pressure drop in the shell side of shell-and-tube heat exchangers. The Kern correlation is essentially based on the Hagen – Poiseuille equation for laminar flow, but flow visualization results presented here show that ...

We demonstrate the construction of corrugated waveguides using stacked rings to propagate terahertz frequencies. The waveguide allows propagation of the same fundamental mode as an optical-fiber, namely, the HE(11) mode. This simple concept opens the way for corrugated wave-guides up to several terahertz, maintaining beam characteristics as for terahertz applications.

The strength of a corrugated container is usually determined and reported as crush strength under progressively increasing top-to-bottom compressive load. The test is performed in seconds in a controlled constant temperature and relative humidity environment. However, a dynamic strength test under controlled conditions cannot account for the reduction in load-carrying ability inherent in the ex...

A 25-year-old woman with complete transposition of the great arteries presented for routine follow-up one year post Mustard procedure. She previously underwent balloon atrial septostomy (Rashkind procedure) early after birth, but her family declined further surgery. She developed progressive pulmonary hypertension early in life, shortness of breath on moderate exertion, followed by progressive ...

Turbulent heat transfer in Helically Corrugated Tubes (HCT) was numerically investigated for pure water and SiO2 nanofluid using Computational Fluid Dynamics (CFD). This study was carried out for different corrugating pitches (5, 7, 8 mm) and heights (0.5, 0.75, 1.25 mm) at various Reynolds numbers ranging from 5000 to 13300. The effect of nanoparticles on heat transfer augmentation for plain t...
