Calculating Rated Power Output & Energy Capture for Marine Current Turbines

AI Thread Summary
To calculate the rated power output for tidal turbines and energy capture per cycle, the user is attempting to define integration limits T1 and T2, with T1 calculated as 186.25 minutes based on a 12-hour and 25-minute cycle. The user seeks assistance in determining T2, while also referencing the velocity equation V = Vmax.sin(wt). A suggestion is made to build a model and test it in a water tank due to the numerous variables involved in fluid dynamics. It is emphasized that fluid flow models do not scale linearly, which adds complexity to the calculations. Accurate modeling and testing are crucial for reliable results in tidal energy capture.

Hi

i am trying to find rated power output for turbine for tidal, and energy capture per cycle i am putting limits to integration T1 and T2 i know i can assume period of 12 hours and 25 mints which is 745 mint for quarter cycle T1 would be 745/4 so T1 is 186.25 but i don't know how cani find T2
we also know V= Vmax.sin wt

can anyone help pls

The best I can think of would be to suggest that you build a model and test it in a water tank. There are so many variables. And remember that models for fluid flow don't scale up by direct proportion.
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
