Thermo-mechanical simulation of frost heave in saturated soils

Frontiers of Structural and Civil Engineering   Pages 1400-1412 doi: 10.1007/s11709-023-0990-x

Abstract: Frost heave-induced damage is one of the winter-related pavement deterioration.The study of frost heave requires conducting a multiphysics analysis, considering the thermal, mechanicalThis paper presents the use of a coupled thermo-mechanical approach to simulate frost heave in saturatedDifferent frost heave scenarios with uniform and non-uniform boundary conditions are considered to demonstrateheave phenomenon, such as water fusion, porosity variation, cryogenic suction force generation, and

Frost heave and freezing processes of saturated rock with an open crack under different freezing conditions

Zhitao LV, Caichu XIA, Yuesong WANG, Ziliang LIN

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 4,   Pages 947-960 doi: 10.1007/s11709-020-0638-z

Abstract: Frost heave experiments on saturated sandstone and tuff with an open crack are conducted under uniformFrost heave of crack in sandstone with high permeability is more significant under uniform freezing conditionHowever, frost heave of crack in tuff with low permeability is more significant under unidirectionalfreezing condition; however, the frost heave of crack would be more significant for low permeabilityTherefore, the freezing condition and rock permeability determine the frost heave of rock with crack

Laboratory experiment on using non-floating body to generate electrical energy from water waves

Arunachalam AMARKARTHIK, Srinivasan CHANDRASEKARAN, Karuppan SIVAKUMAR, Harender SINHMAR

Frontiers in Energy 2012, Volume 6, Issue 4,   Pages 361-365 doi: 10.1007/s11708-012-0210-1

Abstract: This paper describes an innovative method of using a non-buoyant body to harness ocean waves. All the point absorbers are buoyant in nature and move up due to buoyancy and come down because of gravity. The point absorbers are designed to move along the waves to make the device efficient. These devices face excessive stress during the rough weather on account of the extreme motion of waves and cause the total device failure. The present study shows that using a non-buoyant body for conventional point absorber principle is much efficient and safer than any other device proposed till today. A small scale wave energy converter with non-buoyant body was designed, fabricated and tested in small scale wave maker. An electrical generator was coupled with the device to generate electrical energy from harnessed waves. The generator was electrically loaded and the generated power was measured. It was found from the experiments that the proposed device showed a significant improvement in electricity generation and safety during extreme conditions. In addition to the electricity generation, the characteristics of the device were also studied by using various wave and device parameters.
