SIMULATION OF ELECTRIC AND HYBRID VEHICLES IN A VEHICLE SIMULATOR BASED ON A DETAILED PHYSICAL MODEL, FOR THE PURPOSE OF HMI EVALUATION

In this article, we propose a software solution to study HMI of electric and hybrid electric vehicles in vehicle simulators. We will start with the description of a development process of a physical model for HEV simulation in IGNITE software and equation-based language Modelica. A short introduction to the language, its possibilities, and explanation, why it is more suitable for the development of such models (vehicle powertrain), are presented in the first part of the article. A fusion mechanism of the physical engine with the model by means of FMU (Functional Mock-up Interface) is also described in this part The second part is dedicated to the description of the model constructed in third party software IGNITE. This model has a detailed calculation of energy consumption and energy flow based on the selected control strategy. The last part of the article describes a possible experiment methodology

Vapor pressures and thermophysical properties of selected ethanolamines

A thermodynamic study of three ethanolamines, 2-(diethylamino)ethanol, 2-(ethylamino)ethanol and 2- (isopropylamino)ethanol, reporting the measurements of vapor pressure, liquid phase heat capacities, and phase behavior is presented in this work. The vapor pressures were measured using a static method in the temperature interval 238e343 K. After a critical assessment of literature data, selected experimental data were correlated using the Cox equation. The liquid phase heat capacities were measured in the temperature range 265e355 K using Tian-Calvet calorimetry and the phase behavior was investigated using differential scanning calorimetry (DSC) starting from 183 K. For 2-(ethylamino)ethanol and 2-(isopropylamino)ethanol, two monotropically related crystalline forms were identified. To our knowledge, vapor pressure and heat capacity for 2-(isopropylamino)ethanol and phase behavior data for 2-(ethylamino)ethanol and 2-(isopropylamino)ethanol are reported for the first time in this work.The authors acknowledge financial support from the Czech Science Foundation (GACR no. 17-03875S) and the project POCI-01- 0145-FEDER-006984 e Associate Laboratory LSRE-LCM funded by FEDER through COMPETE2020 - Programa Operacional Competitividade e Internacionalização (POCI) e and by Portuguese national funds through FCT - Fundação para a Ciência e a TecnologiaThe authors acknowledge financial support from the Czech Science Foundation (GACR no. 17-03875S) and the project POCI-01- 0145-FEDER-006984 e Associate Laboratory LSRE-LCM funded by FEDER through COMPETE2020 - Programa Operacional Competitividade e Internacionalização (POCI) e and by Portuguese national funds through FCT - Fundação para a Ciência e a Tecnologia.info:eu-repo/semantics/publishedVersio

Vapor pressure and thermophysical properties of eugenol and (+)-carvone

In this work, vapor pressures, liquid-phase heat capacities, and phase behavior of two monoterpenoids, (þ)-carvone and eugenol were studied. The vapor pressure experiments were performed using a static method over an environmentally relevant range of temperatures, from 258 K to 308 K. Liquid-phase heat capacities were measured by Tian-Calvet calorimetry between 265 K and 355 K. The phase behavior was investigated by heat-flux differential scanning calorimetry from 183 K. Experimental data were supplemented by ideal-gas thermodynamic properties obtained by combining quantum chemical and statistical thermodynamic calculations. Vapor pressures and heat capacities obtained in this work along with selected literature values were treated simultaneously by multi-property correlation in order to obtain a consistent description of thermodynamically linked properties. To our knowledge, liquid-phase heat capacities and phase behavior of eugenol are reported for the first time in this work.The authors M.F., K.R., V.

Structure and Glass Transition Temperature of Amorphous Dispersions of Model Pharmaceuticals with Nucleobases from Molecular Dynamics

Glass transition temperature (Tg) is an important material property, which predetermines the kinetic stability of amorphous solids. In the context of active pharmaceutical ingredients (API), there is motivation to maximize their Tg by forming amorphous mixtures with other chemicals, labeled excipients. Molecular dynamics simulations are a natural computational tool to investigate the relationships between structure, dynamics, and cohesion of amorphous materials with an all-atom resolution. This work presents a computational study, addressing primarily the predictions of the glass transition temperatures of four selected API (carbamazepine, racemic ibuprofen, indomethacin, and naproxen) with two nucleobases (adenine and cytosine). Since the classical non-polarizable simulations fail to reach the quantitative accuracy of the predicted Tg, analyses of internal dynamics, hydrogen bonding, and cohesive forces in bulk phases of pure API and their mixtures with the nucleobases are performed to interpret the predicted trends. This manuscript reveals the method for a systematic search of beneficial pairs of API and excipients (with maximum Tg when mixed). Monitoring of transport and cohesive properties of API–excipients systems via molecular simulation will enable the design of such API formulations more efficiently in the future.</jats:p
