Liquid slugs trapped in a voided line may damage the pipe systems used in thermal power plants. Problems in those plants have been reported in the literature. In order to prevent the failures of the pipes, the impact pressures due to slugs should be predicted as accurately as possible. In the present study, slug motion is experimentally investigated. Experiments are conducted to measure impact force due to slug flow for a larger pipe diameter which represent the real piping systems better. An inclined pipe is used in the experiments, which is connected to a pressurized air tank and between them a ball valve is located. A slug mass or the initial slug length before each experiment can be set at the lower part of the pipe by using a water tank at the upstream. By opening the valve the liquid slug is accelerated due to the pressurized air at the tank and hits 90o degree elbow located at the downstream end of the pipe. After the elbow, the system is open to atmosphere with a short pipe segment. The pipe is rigidly attached to air tank and concrete floor. Due to extensive anchoring, the pipe can be assumed to be rigid and constrained from axial movement induced by the slug impact. To measure the pressure history, a pressure transducer is installed on the elbow.Peak pressures at the elbow are measured for different initial slug lengths. The experimental results obtained in this study can be used to validate different numerical approaches.

Experimental characterization of a pressure swirl spray by analyzing the half cone angle fluctuation
Amoresano, A.; Allouis, Christophe Gerard; Di Santo, M.; Iodice, P.; Quaremba, G.; Niola, V (2018-06-01)
Pressure swirl sprays are frequently used in burners for gas turbines like the LPP chamber or to generate diffusion flames. Combustion between fuel and the air is governed by complex phenomena determined by the mixing of the mass flow rate of the two phases liquid and gaseous. Characterization of the spray by measuring the half cone angle fluctuations with a speed camera and a Lagrangian approach allows the working space of the spray to be defined and the "signature" of the spray in well-defined conditions ...
Design and performance analysis of a reversible axial flow fan
Köktürk, Tolga; Eralp, O. Cahit; Department of Mechanical Engineering (2005)
Reversible axial flow fans are used as emergency ventilation fans to discharge the smoke generated on the probable fires occurring in the underground transportation systems and mines as quickly as possible, without causing any harm to people exposed to it. The fans which are placed in different configurations according to the location of fire must be able to work bi-directionally, namely reversible. Due to this fact, the blade profiles of the fan must possess the same aerodynamic performance while working o...
Experimental and computational investigation of the emergency coolant injection effect in a candu inlet header
Turhan, K. Zafer; Yeşin, Ahmet Orhan; Department of Mechanical Engineering (2009)
Inlet headers in the primary heat transport system(PHTS) of CANDU type reactors, are used to collect the coolant coming from the steam generators and distribute them into the reactor core via several feeders. During a postulated loss of coolant accident (LOCA), depressurization and vapor supplement into the core may occur, which results a deterioration in the heat transfer from fuel to the coolant. When a depressurization occurs, “Emergency Coolant Injection(ECI)” system in the PHTS in CANDU reactors, is au...
Experimental and numerical analysis of dry forward combustion with diverse well configuration
Akın, Serhat; Kök, Mustafa Verşan (2002-07-01)
In situ combustion is a thermal recovery technique where energy is generated by a combustion front that is propagated along the reservoir by air injection. Most of the previously conducted studies report thermal and fluid dynamics aspects of the process. Modeling in situ combustion process requires extensive knowledge of reservoir data as well as reaction kinetics data. Unfortunately, limited kinetic data are available on the rates and the nature of partial oxidation reactions and the high-temperature combu...
Experimental study and Taguchi Analysis on alumina-water nanofluid viscosity
Elcioglu, Elif Begum; Güvenç Yazıcıoğlu, Almıla; TURGUT, ALPASLAN; Anagun, Ahmet Sermet (2018-01-05)
Nanofluids as dispersions of fine particles within industrial fluids have potential in thermal applications due to their improved thermal characteristics. On the other hand, their viscosity may be a limitation for forced convective heat transfer, since increase in viscosity increases the pump power requirement. In this study we report experimental results for alumina-water nanofluid viscosity at different temperatures, for different nanoparticle fractions and diameters. Experimental data were collected base...
