In this contribution, a new method referred to as Extended Discrete Element Method (XDEM) is usedto model melting of a single particle in the fluid media. The XDEM as a Lagrangian-Eulerian framework is the extension of Discrete Element Method (DEM) by considering thermodynamic state such as temperature distribution and is able to link with Computational Fluid Dynamics (CFD) for fluid phase. In order to provide more accurate results, multiscale method was used. The model is validated by comparing predicted results with existing experimental data for melting of a single ice particle in a water bath. In addition, the model has the capability to be extended to the packed bed of particles with different size and properties to produce different liquid phases. [less ▲]

High-growth companies intensely contribute to our economies and constitute a particular area of interest for entrepreneurship scholars. Growth is also one of the major indicators of entrepreneurial success in the literature. Female entrepreneurs’ growth intentions and behaviors therefore constitute central questions for researchers in the field. Our contention is to develop a typology of female-managed businesses, differentiating between various growth patterns. We do not consider women entrepreneurs as a homogeneous group, rather taking into account the diversity of existing realities. In order to develop this typology, we rely on an existing French database, Women Equity for Growth, that has been measuring the performances of women-led businesses for five years. [less ▲]

An accurate description of fluid flow through porous media is very important to predict, design and optimize many industrial phenomena principally in condition where experimental studies are difficult to perform. In these kind of problems numerical simulations can help to gain a better process understanding. During last decades many numerical approaches mainly Finite Volume Method (FVM) were applied to model different multiphase flows containing gas, liquid and solid phases. The solid phase may treat by continuous or discrete frameworks. In the former method which is based on Eulerian framework the solid phase is considered as a continuous phase like other fluid phases while in the second method which is based on Lagrangian framework, the solid phase is considered as separate particles. In this study, the flow behavior of several incompressible isotherm phases through solid particles was modelled. The model describes the motion of fluid flows such as gas and liquid phases using continuum approach by applying Computational Fluid Dynamics (CFD) as a numerical method and the solid particles by Lagrangian framework using so-called eXtended Discrete Element Method (XDEM). XDEM is a numerical simulation framework based on classical Discrete Element Methods (DEM) extended by consideration of thermophysical states. A combination of the two numerical methods was performed through momentum and mass exchange between fluid and solid phases which is called combined continuum discrete approach. The solid phase is considered as packed solid particles. The model results demonstrate enormous effect of solid particles on deviation of fluid phases while passing through particles by testing different drag force models. This model was applied to the dripping zone of blast furnace where the liquid phases of liquid iron and slag flow downward through coke particles and gas phase ascends upwards through the shaft which is classified as a counter-current multiphase packed bed reactor. The main goal of this project is to provide a solver which is able to treat several fluid phases through porous media using combined Eulerian-Lagrangian framework by exchanging data between this two approaches.

The aim of this communication is to explore an emergent topic in the entrepreneurship literature, collaborative entrepreneurship, with the perspective of female entrepreneurs in Luxembourg. We share the first insights from an exploratory study on this relatively unexplored topic, in particular in the women's entrepreneurship field. The in-depth case study analysis of two female entrepreneurs who created and developed a business collaboration, complemented by qualitative interviews with female entrepreneurs working in collaboration, enable to propose first elements of understanding of this phenomenon and to establish the bases of a theoretical model.
