impulse buying is a significant aspect of consumer behavior and a critical concept in the marketplace. dramatic increases in consumption and possibility of credit buying all over the world has provided appropriate situations for impulse buying, however there is little information about impulse buying in eastern and in transition societies and economies. the purpose of this study is to develop a...

Numerical simulations were conducted to research the pre-cooling effects of water injection on turbine inlet a turbine-based combined cycle (TBCC) engine under different flight conditions. Then, performance pre-compressor cooling (WIPCC) was calculated by mathematical modelling with air ratios (WAR). It first time that mass field TBCC simulated, and it also subcomponent assessed. The calculatio...

In order to study the effect of alternating fluid–solid action on dynamic characteristics runner a reversible hydraulic turbine, turbine model is used as research object, and two-way coupling method iteratively calculate analyze fluid structural equations obtain under typical operating conditions. The results showed that influence high-speed water ring area certain working condition, incoming f...

In structural health monitoring (SHM), using only the existing noise has long been an attractive goal. The advances in understanding cross-correlations in ambient noise in the past decade, as well as new understanding in damage indication and other advanced signal processing methods, have continued to drive new research into passive SHM systems. Because passive systems take advantage of the exi...

in this paper, the fluid-structure interaction phenomenon and the research history are described. then due to the complex and specific working conditions of a turbine blade, we have investigated the phenomenon on this subject. the fluid-structure interaction on a turbine blade model has been simulated by using structural and fluid flow section of ansys software. a model of turbine blade with ai...
