The temporal development of the mixing field in a decaying jet (Re = 50,000) was quantified by measuring mole fraction and scalar dissipation rate (SDR) decaying, isothermal, turbulent gaseous jet. 2D measured using planar laser induced fluorescence acetone and, with appropriate image processing, this allowed estimation SDR two in-plane components within 16% error. instantaneous averaged distri...

Passive advection of light particles carried by a high viscosity fluid in polymer processing equipment exhibits complex behavior due in part to the non-linearity of the equation of motion. The particles motion also exhibits sensitivity to the initial positions. A fundamental understanding of the influence of initial positions of particles on the quality and rate of distributive mixing is essent...

In dilute aqueous mixtures of the detergent C12EO8 and the phospholipid POPC the phase and partition behavior as well as the transfer enthalpies of the respective molecules between the various states (monomers, bilayers, micelles) have been measured by isothermal titration calorimetry [Heerklotz et al., J. Phys. Chem. 1996, 100, 6764]. To derive more information about the molecular interpretati...

The isothermal vapor + liquid equilibria of carbon dioxide (E)-2-hexenal (a key apple aroma) was measured using a visual equilibrium cell with an analytic methodology. selected isotherms were (313.2, 323.2 and 333.2) K, the pressures assessed ranged from (2.2–9.8) MPa. thermodynamic consistency experimental data verified, uncertainties molar fractions phases estimated. density dynamic viscosity...

This paper presents the results of experimental measurements and computational fluid dynamics (CFD) simulations of the indoor environment of an open-plan office. The measurements were conducted in the Indoor Environment Research Facility (IERF) at IRC/NRC, in which six mock-up were setup to simulate an interior open-plan office. Two scenarios were investigated: isothermal and non-isothermal. Th...

Isothermal titration calorimetry (ITC) experiments were performed for investigation of binary mixtures comprised the Brønsted superbase DBN with hydrogen ethanoate (AcOH). The heat mixing (HE) profile was recorded at (343.15 ± 0.1) K and fitted a 5-parameter Redlich-Kister (RK) polynomial. RK fit parameters subsequently used to quantify partial molar heats mixing, xiHiE, each component i. ITC-b...

The behavior of the dielectric constant epsilon of pure fluids and binary mixtures near liquid-gas and liquid-liquid critical points is studied within the concept of complete scaling of asymmetric fluid-fluid criticality. While mixing of the electric field into the scaling fields plays a role, pressure mixing is crucial as the asymptotic behavior of the coexistence-curve diameter in the epsilon...

This work focuses on characterizing the integral features of atomic diffusion in Ni/Al nanolaminates based on molecular dynamics (MD) computations. Attention is focused on the simplified problem of extracting the diffusivity, D, in an isothermal system at high temperature. To this end, a mixing measure theory is developed that relies on analyzing the moments of the cumulative distribution funct...

A finite element method is used here to simulate the temperature field, the thermosolutal convection, the solute segregation, and the non-isothermal phase transformation during the growth of ZnTe crystal via the temperature gradient solution growth technique (TGSG) with an accelerated crucible rotation technique (ACRT). Three different trapezoid-wave ACRT sequences are proposed, and their effec...
