# - "(T)" denotes the turbine
# - "(O)" denotes the outlet
# - "*" denotes a fictitious junction

#
# Initially the fluid is at rest at ambient conditions, the shaft speed is zero,
# and no heat transfer occurs with the system.
# The transient is controlled as follows:
# * 0 - 100 s: motor ramps up torque linearly from zero
# * 100 - 200 s: motor ramps down torque linearly to zero, HTC ramps up linearly from zero.
# * 200 - 300 s: (no changes; should approach steady condition)
