Row phenomena of a air -water two-phase mixture in a horizontal capillary return bend are investigated with special attention on the flow pattern and total pressure loss of the bend to obtain the fundamental knowledge about important parameters for designing compact heat exchangers. Pipe inner ...
Liquid film thickness behaviour within a large diameter vertical 180° return bend 2014, Chemical Engineering Science Citation Excerpt : They claimed that the local flow rate of droplets in the gas core in horizontal pipe flow reaches a minimum near the lower wall of the pipe and a maximum near...
Things don't just start moving by themselves. There must be a force acting on the water in the pipe for it to move, and the obvious one is its own weight. Water is quite heavy stuff - a litre of it weighs a kilogram. The water in the tank pushes down on the water in the pipe....
Suppose the pipe runs vertically, then horizontally under a floor, then down vertically again. The water in the horizontal section has weight too - won't this add to the down-force? Well, no, it won't, for the same reason as before - weight acts downwards on that section of pipe, no...
In this paper, we conducted computational fluid dynamics-based design optimization for the water scooping system of a specific type of amphibious aircraft. Design variables for the scoop structure are determined, including the radius of tube bend (Radius_tube), distance from the horizontal baffle to...
Supercritical flows in channel bends, e.g., in steep streams, chute spillways, and flood and sediment bypass tunnels (SBTs), experience cross-waves, which undulate the free surface. The designs of these hydraulic structures and flood protection retaining
One of the major problems of using nanofluids in heat exchange applications is the forming and deposition of nanoparticles on the inner surface of the heat exchanger. In this paper, Water-Cmc fluid is used as a surfactant for nanoparticles to prevent dep
Make it a competition by keeping score of how low each participant can go without touching the water, or simply enjoy the fun of seeing who can twist and bend the most. Don’t forget to capture the priceless moments on camera as everyone twists and contorts their bodies to limbo under ...
The inlet pipe of the in-line centrifugal pump has to redirect the horizontal water flow from the Heating, Ventilating Air Conditioning (HVAC) system towards the vertical flow in the eye of the impeller. This requires a 90 degree bend within the inlet pipe, which generates a rotational seconda...
A bridge to the future Flexible footbridge prototype: a cell unit capable of absorbing horizontal forces. Courtesy of Lars Erik Elseth. IaaC student Lars Erik Elseth has seen firsthand how new approaches in architecture can adapt to changing water needs. Originally from Scandinavia, Elseth grew ...
