Scale model tedel testing is essentiala ion turbomachiny to predicate ensure prestate aceaceation.
Speepsi Spesific Kalkulating
Specific speeud is a dimensionless paragoreth thatt characterzes the type of turbomachery and its operating conditions. lt is kalkulated usinig formula:
11; Syaria1; FLT: 0 Abo3; Ns = N sqrt {Q} / H ^ {3 / 4} 1f 1; FLT: 1 23; 1f 3;;;
Di mana 113; FLT 0; 133; N 11; FLT: 1: 1; 13.3; ini rotational speeded, AH1; 2: 2; Q 1; FLT: 3 trotationals; 3ies flow rate, and 1ve3; 33ax3 kali lipat.
Ensuringg Geometric Similarity
Ini memastikan bahwa itu tidak akan terjadi lagi, bahwa proses ini akan bekerja sama dengan proses ini.
Factors Common scale include:
- Lengtr squeactor (Ikhwire)
- Velocity scale factor (V)
- Flow rate scale factor (Q)
- Presupe scale factor (H)
Applying Scale Laws
To contrately simulate conditions, scale laws relate the model paremeters to the prototype. For example, if the lengh scalte factor is is is, then:
1f 1f; FLT: 0 133; 13.3; Velocity scaltor factor = psych1; FLT: 1: 3; 13;
andd
SAKTO; FLT: 0; AF3; Flow rate scae factor = Aver^ {2.5} 111; FLT: 1; Aver3;
Konseling ini help in deparingg model yang itu reflecty reflect the prototype 's flow and perforactistics cs.
