AIRCRAFT DIESEL ENGINE TURBOCOMPOUND OPTIMIZED

JP Journal of Heat and Mass Transfer, 2015
In order to optimize the design of the thermodynamic cycle of a turbine (Brayton cycle) for using modern common rail as an “active” combustion chamber, it was intended to write the present paper. About the present case, the “active” combustion chamber produces a large amount of the mechanical energy that drives the fan.

Dynamic Models of Mechanical Seals for Turbomachinery Application

Lubricants
One of the primary causes of mechanical face seal failure is rotor vibration. Traditional dynamic seal models often cannot fully explain failure mechanisms. The dynamic models of seals proposed in this paper, including those developed by the authors, are
