Submarine hydrodynamics for off-design conditions
Journal of Ocean Engineering and Marine Energy, 2022 AbstractTraditionally, submarine hydrodynamic design has focussed mainly on requirements regarding operational range, powering performance and manoeuvring ability for deeply submerged conditions. To improve the effectiveness of the boat, attention is also paid to operating near or at the surface and fortunately, computational tools and experimental ...

Off-design performance analysis of gas turbines [PDF]
Global Journal of Engineering and Technology Advances, 2020 This work deals with the off-design performance analysis of gas turbines. Two gas turbine power stations in Rivers state, Nigeria were used as case studies. Ambient temperature-induced off-design calculations were carried out. This is because no gas turbine operates at its design point in the field and ambient temperature is one of the parameters that ...
