Long-term creep of encased polymer liners
… the long-term creep behavior of encased polymer liners.;Short-term tests, following the ASTM D790 procedure, were conducted on pipe liner samples to determine the initial elastic modulus and compare it to the elastic modulus obtained from long-term testing of the encased liner.;Long-term tests …

Bore polishing of diesel engine cylinder liners
There are two important omissions in the literature on bore polishing, firstly there is no evidence of the successful development of a reliable tribo test device to simulate bore polishing and secondly, the mechanism of bore polishing has not been fully defined. The aims of this study were: 1. To …

Long-Term Performance of HDPE Geomembranes as Landfill Liners
High density polyethylene (HDPE) geomembranes are normally used as part of a composite liner for waste containment facilities such as municipal solid waste (MSW) landfills and heap leach pads. Field conditions, which include physical stresses on the geomembrane, elevated operating temperatures, and …

HYDRAULIC PERFORMANCE OF GEOSYNTHETIC LINERS IN TAILINGS STORAGE FACILITIES
Experiments are conducted to investigate the impact of fines content on the compressibility and permeability of the cyclone tailings, and to quantify leakage through a GMB hole overlain by saturated tailings. The effect of hole shapes, hole sizes, GMB thicknesses, tailings thicknesses, tailings …

Numerical investigation of slat noise attenuation using acoustic liners
… attenuating slat noise using absorptive acoustic liners in the slat/main element gap is explored using a time domain computational aeroacoustic (CAA) technique. The aims of the development and application of the computational method are to reveal the mechanism of the slat noise generation and …

Numerical study of solute transport in deformable soil liners
… the migration of VOCs in unsaturated landfill liners with continuous air phase. In the formulation, vertical soil stress, capillary pressure, air pressure, temperature increase and dissolved solute concentration were selected as primary variables. The finite deformation was addressed by use of …

Dimensional Stability of Geosynthetic Clay Liners in Landfill Applications
… the dimensional stability of geosynthetic clay liners (GCLs) in landfill applications. Multiple occurrences of panel separation of overlap seams in GCLs have been documented; however, explanation for the relative contribution of various mechanisms causing shrinkage has been limited. A systematic …

Experimental testing of bimetallic and reactive shaped charge liners
… investigate small scale bimetallic and reactive liners and to record the target deformation characteristics of larger scale reactive liners. Tests 1 - 9 used liners of 20.02 mm diameter and were conducted in either a containment tube that housed an array of target plates or in a large blast tank …

Acoustic performance of bias flow liners in gas turbine combustors
Der Einsatz moderner Verbrennungskonzepte zur Effizienzsteigerung und Schadstoffreduktion bei Gasturbinen wird oft durch thermo-akustische Instabilitäten verhindert. Durchströmte Brennkammerliner können die akustische Dämpfung des Systems erhöhen und die Instabilitäten unterdrücken. Eine …

Development and Use of Moisture-Suction Relationships for Geosynthetic Clay Liners
… relationships of geosynthetic clay liners (GCLs). Moisture-suction relationships were determined by combining suction data from pressure plate tests, contact filter paper tests, and relative humidity tests, then fitting water retention curves (WRCs) to the data. WRCs were determined …

Selected factors affecting measurement of the hydraulic conductivity of geosynthetic clay liners
Geosynthetic clay liners (GCLs) are thin (~7 to 10 mm), factory manufactured hydraulic barriers typically comprising a layer of sodium bentonite sandwiched between two geotextiles. Upon hydration and permeation with water at low effective stress (σ´) (e.g., typically ≤ ~30 kPa [4 psi]), the …

Experiments and Impedance Modeling of Liners Including The Effect of Bias Flow
… of normal impedance of perforated plate acoustic liners including the effect of bias flow was studied. Two impedance models were developed, by modeling the internal flows of perforate orifices as infinite tubes with the inclusion of end corrections to handle finite length effects. These models …
