Impact of change in exchange rate on foreign direct investment: evidence from China

Based on the monthly data of foreign direct investment (FDI) in China and the index of real effective exchange rate (REER) of RMB during Jan 1997 to Sep 2012, we develop a statistical model in this paper to test the impact of changes in exchange rate in the host country on FDI, with reference to international and domestic research. According to the results of the empirical test, the appreciation of RMB promotes FDI after the reforms in the exchange rate regime in 2005 and this phenomenon is a result from the change in the type of FDI into China in recent years. In the long term, the proper appreciation of RMB and a more flexible exchange rate regime will impact on China\u27s currency and micro-control policies positively

Numerical simulation analysis of large eddy simulation for T-tube based on solid-liquid two-phase abrasive flow

As a kind of nano machining technology, abrasive flow polishing technology plays an important role in precision machining region. As an important numerical simulation method in fluid mechanics, large eddy numerical simulation method has become an important method for many scholars to study abrasive grain polishing technology. In this paper, the use of fluid mechanics software FLUENT and selected Mixture mixed model. Based on the theory of solid-liquid two-phase flow dynamics, the large-eddy numerical simulation method was used to study the polishing process of T-tube abrasive flow, and the micro-machining mechanism of abrasive-polished workpiece was discussed. The influence of the different inlet velocities on the polishing effect of the abrasive grains was discussed by analyzing the numerical simulation results of the different inlet velocities of the abrasive grains during the processing of the T-tube

Numerical analysis for viscosity temperature characteristics of abrasive flow finishing on micro-bore nozzle

Abrasive flow machining has become an efficient and economical ultra precision process for machining micro-bore parts. In this paper, aiming at viscosity temperature characteristics of abrasive flow finishing on micro-bore nozzle, under the guidance of the three governing equations of fluid mechanics theory, mixed phase model and discrete phase model were conducted, FLUENT software was resorted to simulate the discrete and fluid phase numerical characteristics of the solid-liquid two-phase flow field in the nozzle orifice with various field temperature and viscosity of slurry, the mechanism of erosion and wear of particles and effect of different processing parameters on particle erosion rate were uncovered, which provides a theoretical basis for the nozzle structure of abrasive flow machining
