Design and manufacturing a small-scale radial-inflow turbine for clean organic Rankine power system

“…Moreover, the evaluation of the aerodynamic characteristic and performance of the RIT turbine requires creating the blade geometry and modifying it and testing it using CFD simulation in more detail. More details about the blade generation of RIT can be found in Al Jubori et al (2017b).…”

Design and off-design optimisation of an organic Rankine cycle (ORC) system with an integrated radial turbine model

“…The Jones data are widely used for CFD code validation since Sauret (2012) rediscovered this case and presented CFD results. Several authors (Sauret 2012, Keep et al 2017, Al Jubori et al 2017 predicted higher efficiencies of between two and four percentage points. Odabaee et al (2014) however, calculated a considerably smaller efficiency by about 5-6 percentage points whilst Gad-el Hak et al (2017) got a nearly perfect match (within 0.3 percentage points).…”

Investigation of organic Rankine cycle integrated with double latent thermal energy storage for engine waste heat recovery

“…The mainstream methods to investigate ORC technologies include the investigation of different ORC working fluids [13,14], optimisation of system parameters [15,16], design and optimisation of components [17] such as heat exchanger and expander, and the design of system configurations. Wang et al [13] proposed a method to select working fluids and conduct parametric optimisation using a multi-objective optimisation model based on the simulated annealing algorithm.…”

“…Particle swarm optimisation algorithm is adopted to study the key geometric parameters of the fin-and-tube evaporator including the inlet radius of tube side and a shell side, height and thickness of fins and fin spacing. Ayad M. et al [17] used small-scale axial, radial-inflow and radial outflow turbines on a small scale ORC system and compared their performances under their single and two stage configurations based on three-dimensional CFD analysis. Results indicated the two-stage axial and radial-outflow configurations can achieve a considerably better performance [17].…”
