Scaling Parameters Sample Clauses

Scaling Parameters. The prototype design was derived in prototype scale to ensure the required performance according to the ALPHEUS description, and to guarantee the strength of the blades at full scale. To account for limitations at the lab an appropriate model scale was derived based on scaling laws for hydraulic machines. The scaling laws assume that the flow coefficient, work coefficient, and power coefficient are constant between the prototype and model scales. This leads to relationships between the model and prototype scales as

This leads to relationships between the model and prototype scales as , = (, )3 (, ) (1.1) , , , , = (, )2(, )2 (1.2) , , , , = (, )5(, )3 (1.3) , , , Here Q is the flow rate, Ω is the rotational speed of the runner, H is the head, and P is the power. Subscripts p and m represent prototype and model scales, respectively, and i indicates runner 1 or 2, since there are two runners.
