| Unit System | Metric (m, kg, N, s, V, A) |
| Angle | Radians |
| Temperature | Kelvin |
Material properties for the steel blade in MKS units are as follows:
| Blade Material Properties | |
|---|---|
| Thermal Conductivity | 43 W m^-1 C^-1 |
| Young's Modulus | 2.00E+11 Pa |
| Poisson's Ratio | 0.3 |
| Coefficient of Thermal Expansion | 1.08E-5 C^-1 |
Fluid properties in MKS units are as follows:
| Fluid Material Properties | |
|---|---|
| Thermal Conductivity | 1.00E-16 |
| Specific Heat | 2.26E+3 |
The convection coefficients, inflow temperatures, and mass flow rates are specified. The heat transfer from the blade to the coolant is proportional to the film coefficient, and the temperature rise in the fluid is inversely proportional to the mass flow rate.
The convection film coefficients in W/(m2K) are as follows:
| Hole Number | Film Coefficient |
|---|---|
| 1 | 2.9543e5 |
| 2 | 2.9629e5 |
| 3 | 3.0076e5 |
| 4 | 3.1416e5 |
| 5 | 3.1495e5 |
| 6 | 3.0199e5 |
| 7 | 3.0247e5 |
| 8 | 4.4343e5 |
| 9 | 2.8527e5 |
| 10 | 8.9586e5 |
