A detailed mechanistic model has been developed for scroll compressors and scroll expanders with liquid flooding for application to the Liquid Flooded Ericsson Cycle. This model is based on the integration of a set of differential equations that arise from the conservation laws. The impact of the flooding liquid on the working process is also included through mixture properties as well as treatment of two-phase flow pressure drop. With the working process known, it is then possible to solve for the compressor power, total mass flow rate and other model outputs. The fine level of detail in the model allows for the investigation of the impact of design changes to the scroll machines. This model can also be readily extended to allow for the analysis of liquid flooded vapor compression refrigeration. [less ▲]

In the field of liquid-liquid extraction a variety of new processes like extraction from fermentation broths, aqueous two-phase systems or extraction with high viscous media is investigated in the recent years. Process engineers often do not have broad experience with these special applications of liquid-liquid extraction. Therefore it is necessary to find a metric to estimate the quality of a design solution and to compare different possible liquid-liquid extraction processes at an early stage of the design process. One possibility is to define an evaluation criterion like for example the overall process costs, which is determined for each option, and explicitly consider uncertainties in the design variables. A framework for an easy comparison of different liquid-liquid extraction processes ranging from various solvents to diverse equipment during every stage of the process development is presented. Using uncertainty propagation the overall uncertainty of the chosen evaluation criterion is estimated. As each step of a design process is meant to reduce uncertainty about the final solution of the design challenge the following design steps are proposed in a way that the new information has the highest possible impact on deciding whether a process option is further investigated or not regarded in the next step. Within this framework it is possible to make sound decisions yet at an early stage of the process development and allocate resources for the process and equipment design in an efficient manner. To keep track on all investigated alternatives and decisions, results can be visualized and documented in option trees. In this presentation an algorithm considering uncertainties in the design of liquid-liquid extraction is introduced and its general application on the design process is discussed. [less ▲]

A travers ce travail doctoral, nous cherchons à étudier l’influence des mécanismes de gouvernance d’entreprise sur la liquidité des titres. Nous nous focalisons aussi sur l’efficacité et la qualité du système de gouvernance en passant d’une étude fragmentée des mécanismes de contrôle à une étude systémique de la gouvernance d’entreprise. Les résultats défendent une orientation législative française envers l’adoption de certaines normes pour la bonne conduite de la gouvernance d’entreprise. L’étendue des informations publiées dans les rapports annuels augmente la visibilité d’une entreprise, réduit éventuellement l’asymétrie d’informations et augmente la liquidité des titres. Ces effets sont d’autant plus prononcés par l’application des normes IFRS rendues obligatoires à partir de 2005. Par ailleurs, nous montrons que le développement de la demande d’actionnariat institutionnel est une nécessité pour le marché parisien, afin de favoriser sa croissance de façon générale et soutenir sa liquidité. Nous mettons en évidence également un impact positif de la taille du conseil d’administration, de l’indépendance et de l’expertise financière des administrateurs, et du nombre des réunions du conseil sur la liquidité des titres. De même, le comité d’audit offre un support indispensable pour prévenir le risque « d’illiquidité ». [less ▲]

Liquidity commonality exists and empirical evidence (e.g. Lin et al., 2011) indicates that exposure to this common liquidity factor is priced in the cross-section of corporate bonds. The existence of commonality implies that part of a bond’s illiquidity is left as idiosyncratic. In this paper, we study how illiquidity components explain the cross-section of bond yields and how this relationship varies over time and across bond categories. We use a factor decomposition to break down total illiquidity into a common and an idiosyncratic component and analyze how yields relate differentially to each of these two components. We find that a bond’s idiosyncratic illiquidity is important, which might reflect informational asymmetries compounded by the lack of diversification in the institutional investors’ portfolios. Moreover, the relation between illiquidity and yield spreads appears to be negative during the recent crisis period. [less ▲]
