The swirling flow of sudden‐expansion dump combustor with central V‐gutter flameholder and six side‐inlets is studied by employing the SIMPLE‐C algorithm and Jones‐Launder k‐ε two‐equation turbulent model. Both combustion models of one‐step with infinite chemical reaction rate and two‐step with finite chemical reaction rate of eddy‐breakup (EBU) model are used to solve the present problem. The results agreed well with available prediction data in terms of axial‐velocity and total pressure coefficient along combustor centerline. The flowfield structure of combustor considered is strongly affected by swirling, flameholder and side‐inlet flow. For the fixed strength of swirling, the length of central recirculation zone is decreased when the angle of V‐gutter is increased. The outlet velocity of combustor in reacting flow is higher than that in cold flow because the released heat of combustion causes the decrease of density throughout the combustor flowfield. The distribution of mass fraction of various species in reacting process depends on the mixing effect, chemical kinetic and the geometric configuration of combustor.

Taiwan's semiconductor industry continues moving out to China, therefore Taiwan's semiconductor distributors must cooperate with the local distributors in China in order to survive. The purpose of this paper is to discover the key factors considered by Taiwan's semiconductor distributors when selecting partners in China.

This study summarizes the factors from the literatures and the experts' discussion, then develops a hierarchical structure. Using DEMATEL and MMDE to construct the causality of the dimensions, which are then taken as the basis for the development of the analytic network process (ANP) framework. Finally, it gets the weight values of various factors through the results of ANP, which serves as a proposal to discuss how Taiwan's professional semiconductor distributors select partners in China.

According to the weight of the ANP, results show that trust and commitment, scale, market share and corporate culture are factors that increase the possibility of collaboration.

China has become a favorite for foreign investments. Taiwan's semiconductor distributors must actively expand the China market in order to maintain their survival. This study focuses on Taiwan semiconductor distributors who want to invest and establish factories in China, and investigates the key factors that are involved in the selection of partners for Taiwan semiconductor distributors. The results can increase the chances of success among cooperative members.
