(author), Riva, R.E.M. (author), Slobbe, D.C. (author), Klees, R. (author), Zijlema, Marcel (author), Katsman, C.A. (author)The mesoscale variability in the Caribbean Sea is dominated by anticyclonic eddies that are formed in the eastern part of the basin. These anticyclones intensify on their path westward while they pass the coastal upwelling region along the Venezuelan and Colombian coast. In this study, we used a regional model to show that this westward...journal article 2019

Van Westen, T. (author)In this thesis I aim to contribute to a molecular understanding and -description of the phase behaviour of liquid crystalline materials. In particular, I aim at the development of a molecular-based equation of state (EoS) for describing nematic (only orientationally ordered) liquid crystals (LCs) and their mixtures. Special emphasis is put on...doctoral thesis 2015

Van Westen, T. (author), Oyarzun Rivera, B.A. (author), Vlugt, T.J.H. (author), Gross, J. (author)We develop an equation of state (EoS) for describing isotropic-nematic (IN) phase equilibria of Lennard-Jones (LJ) chain fluids. The EoS is developed by applying a second order Barker-Henderson perturbation theory to a reference fluid of hard chain molecules. The chain molecules consist of tangentially bonded spherical segments and are allowed...journal article 2015

Van Westen, T. (author), Vlugt, T.J.H. (author), Gross, J. (author)We study the isotropic (vapor and liquid) phase behavior of attractive chain fluids. Special emphasis is placed on the role of molecular flexibility, which is studied by means of a rod-coil model. Two new equations of state (EoSs) are developed for square-well- (SW) and Lennard-Jones (LJ) chain fluids. The EoSs are developed by applying the...journal article 2015

Oyarzun, B. (author), Van Westen, T. (author), Vlugt, T.J.H. (author)The isotropic-nematic phase equilibria of linear hard-sphere chains and binary mixtures of them are obtained from Monte Carlo simulations. In addition, the infinite dilution solubility of hard spheres in the coexisting isotropic and nematic phases is determined. Phase equilibria calculations are performed in an expanded formulation of the Gibbs...journal article 2015

Van Westen, T. (author), Vlugt, T.J.H. (author), Gross, J. (author)An analytical equation of state (EoS) is derived to describe the isotropic (I) and nematic (N) phase of linear- and partially flexible tangent hard-sphere chain fluids and their mixtures. The EoS is based on an extension of Onsager’s second virial theory that was developed in our previous work [T. van Westen, B. Oyarzún, T. J. H. Vlugt, and J....journal article 2014

Van Westen, T. (author), Oyarzun, B. (author), Vlugt, T.J.H. (author), Gross, J. (author)An extension of Onsager's second virial theory is developed to describe the isotropic-nematic phase transition of tangent hard-sphere chain fluids. Flexibility is introduced by the rod-coil model. The effect of chain-flexibility on the second virial coefficient is described using an accurate, analytical approximation for the orientation...journal article 2013

Oyarzun, B.A. (author), Van Westen, T. (author), Vlugt, T.J.H. (author)he liquid crystal phase behavior of linear and partially flexible hard-sphere chain fluids and the solubility of hard spheres in hard-sphere chain fluids are studied by constant pressure Monte Carlo simulations. An extensive study on the phase behavior of linear fluids with a length of 7, 8, 9, 10, 11, 12, 13, 14, 15, and 20 beads is carried out...journal article 2013

Van Westen, T. (author), Vlugt, T.J.H. (author), Gross, J. (author)Onsager-like theories are commonly used to describe the phase behavior of nematic (only orientationally ordered) liquid crystals. A key ingredient in such theories is the orientation-dependent excluded volume of two molecules. Although for hard convex molecular models this is generally known in analytical form, for more realistic molecular...journal article 2012
