Adiabatic Flow with Friction
Adiabatic flow refers to the flow of fluid without any heat transfer taking place. In such a flow, the energy of the fluid is conserved and the stagnation temperature remains constant along a streamline. However, in the presence of friction, the energy of the fluid is transferred to the surroundings due to the flow resistance offered by the wall of the pipe or channel.
Effect of Friction on Stagnation Temperature
The stagnation temperature is the temperature that a fluid would reach if it were brought to rest isentropically. In adiabatic flow with friction, the stagnation temperature along a streamline remains constant. This is because the heat generated due to friction is assumed to be negligible compared to the energy of the fluid.
The energy of the fluid is dissipated due to friction in the form of heat, which is transferred to the surroundings. However, the amount of heat generated is negligible compared to the energy of the fluid, and hence the stagnation temperature remains constant.
Conclusion
In summary, the stagnation temperature along a streamline in adiabatic flow with friction remains constant. This is because the heat generated due to friction is assumed to be negligible compared to the energy of the fluid.
