Experimental investigation of solid holdup in twin-cyclone combustor [PDF]
Research & Knowledge, 2016 In this study, the hydrodynamics behaviors and solid holdup in a twin-cyclone combustor with a swirling fl uidized bed were investigated under a wide range of cold–air operating conditions. Silica sand of three different particle size ranges: 600–710 μm,

No Holdup in Dynamic Markets [PDF]
SSRN Electronic Journal, 2018 In many markets, heterogenous agents make non-contractible investments before bargaining over both who matches with whom and the terms of trade. In static markets, the holdup problem—that is, inefficient investments caused by agents receiving only a ...

Mass shedding rate of an isolated high-speed slug propagating in a pipeline
Engineering Applications of Computational Fluid MechanicsAn isolated liquid slug in the pipeline can accelerate and achieve a high speed when subjected to a driving pressure. During the slug’s high-speed movement in a pipeline, part of the liquid will shed from it resulting in changes in the slug’s mass and ...

Holdup and Comparative Advantage [PDF]
SSRN Electronic Journal, 2013 We consider a setting where fims need to make irreversible investments to exploit a country's comparative advantage. Firms are then susceptible to ex-post rent extraction by a transit country or by other agents that are able to limit access to world markets. We develop a general equilibrium model where this potential holdup problem makes such countries
