Waterjet peening is a recent promising method in surface treatment. It has the potential to induce compressive residual stresses that benefit the fatigue life of materials similar to the conventional shot peening process. However, there are no analytical models that incorporate process parameters (i.e., supply pressure, jet exposure time, and nozzle traverse rate, etc) to allow predicting the optimized peening process. Mathematical modeling of high-pressure waterjet peening was developed in this study to describe the relation between the waterjet peening parameters and the resulting material modifications. Results showed the possibility of using the proposed mathematical model to predict an initial range for effective waterjet peening under the variation of waterjet peening conditions. The high cycle fatigue tests were performed to validate the proposed model and fatigue test results showed good agreement with the predictions.

Physical Absorption

Removal of CO2 had been one of the main issues facing in worldwide. Intensive researches are still going on to effectively reduce CO2 at low cost. Physical absorption is one of the well-established technologies used to removal CO2 from other gases. The physical absorption process is simple; whereby it contains only one gas liquid contactor and a series of flash tank to regenerate solvent. The CO2 will be absorbed in the physical solvent in the high pressure gas liquid contactor and flashed out in the medium and low pressure flash tank. The advantage of using physical solvent is that the CO2 is absorbed without any chemical reaction involved, thus it can be flashed out easily by reducing the pressure, passing inert gas through the solvent and mild thermal regeneration. The physical absorption is the best operated at high pressure and low temperature as the solubility of CO2 in the solvent is high at the particular condition. Researches carried out currently are focusing on solvent development, absorption and desorption process development and mathematical modeling.

Составлена математическая модель совместных сейсмических колебаний высоконапорной плотины, водохранилища и двух слоев массива грунта под основаниями плотины и водохранилища. Модель представляет контактную краевую задачу математической физики в которой учтены взаимозависимости колебательных процессов в грунтовой толще, в плотине и в водохранилище при распространении гармонической сейсмической волны в рассматриваемой системе. В результате решения поставленной задачи получены расчетные формулы для вычисления относительных амплитуд сейсмических колебаний гребня и основания плотины. The mathematical model of the co-seismic vibrations of high-pressure dams, reservoirs and two layers of soil under the foundations of the dam and reservoir is created. The model represents the contact boundary value problem of mathematical physics which takes into account the interdependence of oscillatory processes in soil, in the dam and in the reservoir during the propagation of harmonic seismic waves in the system under consideration. As a result of solving the tasks the formulae are derived to calculate the relative amplitudes of the oscillations of the top and the base of the dam.
