Part 2

A turbine manufacturer uses three mathematical models to estimate temperature distribution across the face of the turbine wheel under running conditions.


The three models used are:


Model 1:  = 45T


Model 2:


Model 3:


The turbine wheels are as below:




It is necessary that the temperature drops to sensible levels across the disc face. Consequently, the design specification is that, for a temperature at the blade tips (Point A), of 420°C, the temperature at Point B should not exceed 200°C, and the temperature at the bottom of the blade, Point C, should not exceed 125°C


The total blade length from A to C is 55mm, and the distance from B to C is 40mm.



Solve the three equations above, using the initial values given in the manufacturers specifications.

15 marks







Part 3


Produce a set of graphs to establish which of the three models is the most suitable in terms of the design specification.


You should be able to plot the temperature change across the face of the disc, identifying the temperature at point B in each case.


15 marks

Part 4

The piston acceleration of an engine on test is defined by:






(i)      Produce an expression for the velocity,  , using appropriate                                      boundary conditions

10 marks


(ii)     Prove that an expression for the displacement, s, could be represented                        by:   and consequently that                     maximum displacement is equal to 2r

10 marks

(iii)    Plot the graphs of acceleration, velocity and displacement against                      crankshaft angle θ using          suitable axes, and given that r = 10cm,                                   l = 18cm and ω = 50π rad/s
