Readily available processing hardware and "off-the-shelf" (OTS) simulation software has made "high fidelity" first principles models of both steady and transient states, for both axial and centrifugal industrial compressors, relatively easy to construct. These high-fidelity models are finding their way into "real-time. digital twin" performance monitors, front-end engineering design, and post-design – pre-construction compressor performance evaluation. The compressor models are useful for reliably demonstrating the compressor and – to some degree, based on the complexity of the model – process response to various operating conditions. Once the model is constructed, it is trivial to run a "what-if" analysis of compressor performance to answer questions related to (a) recommendations or validation of the recycle/vent valve size and actuation speed, (b) general piping layout and sizing around the compressor, (c) and hot gas bypass requirements, to name a few. This paper takes a practical approach in discussing the compressor and process parameters necessary for building these dynamic "high-fidelity" industrial-compressor models. We identify compressor inputs and compressor responses that are faithfully modeled by first-principle equations available in the simulation software and those that typically require a compromise between an "ab initio" and data-fitting approximation. We discuss the simulation's tendency to overstate pressure excursions during surge events and understate the compressor operation in the "stonewall" region. We also discuss using the simulator software's compressor-stage enthalpy calculations to predict and quantify the compressor train reverse rotation. We use our broad experience and understanding of the compressor operation and simulation and our experience with the AVEVATM Dynamic-Simulation "OTS" simulation software as the basis for this discussion.

In this paper, a numerical model for predicting the working parameters of the cold rolling mill process in full film lubrication is presented. The model is useful from an industrial point of view, because it can forecast the thickness reduction of the metal sheet and the pressure trend, so that the rolling mill process parameters can be regulated to obtain a specific output thickness. Experimental tests were performed, and results are compared to the theoretical ones resulting from the model. The novelty of the proposed model is that it combines Orowan’s theory for the plastic deformation analysis with the Reynolds equation in full film lubrication and the continuity conditions. The lubricant flow and viscosity are studied, taking in account their dependence on pressure and temperature. The proposed model describing the full film regime is also compared to another one, previously proposed by the authors, based on the well-known slab analysis and sharing with it the representation of the lubrication regime, the mathematical procedure, and the boundary conditions. The results show that the proposed model provides a better prediction of the working parameters with respect to the model based on the slab analysis.

Background: It is important to identify the risks that may cause skin cancer development in adolescents and the factors affecting sun protection behaviors. Objectives: This study was carried out in a descriptive and cross-sectional design to determine the effect of high school students’ self-efficacy and perceptions for sun protection on their sun protection behaviors. Methods: The study was conducted from February to April 2019 with 846 students from two high schools in Turkey. The data of the study were collected using a personal information form, the Sun Protection Behavior Scale (SPBS), the Decisional Balance Scale (DBS) for Sun Protection, and the Self-Efficacy Scale for Sun Protection (SES). The data were analyzed through SPSS and AMOS software packages using Pearson’s correlation analysis, the linear regression analysis, and the structural equation model. Results: In the multiple regression analysis, a model was created according to the relationship between the variables. In the model, high school students’ self-efficacy and perceptions for sun protection explained 33.6% of their sun protection behaviors. It was found that all the factors except for DBS cons perception (p> .05) had a statistically significant effect on students’ sun protection behavior. According to the structural equation model, the fit indices of the model were found to be greater than .91. Conclusion: As adolescents’ self-efficacy levels and perceptions of the pros and cons increase, their likelihood of exhibiting sun protection behaviors increases as well. In adolescent training, it is important to design and disseminate educational programs consisting of interventions that will increase adolescents’ self-efficacy and perceptions of decision-making.
