Heat exchangers (HEs) are often modeled using pinch point temperature difference (ΔT_pinch) methods when optimizing systems with HEs. However, even small inaccuracies in model predictions of HEs will introduce numerical noise that can cause optimization algorithms to fail. A recent study of single HEs suggests that highorder interpolation methods can compute ΔT_pinch much faster ...

Optically thin layers of tiny ice particles near the summer mesopause, known as noctilucent clouds, are of significant interest within the aeronomy and climate science communities. Groundbased optical cameras mounted at various locations in the arctic regions collect the dataset during favorable summer times. In this paper, first, we compare the performances of various deep learningbased image ...

The efficient transportation of large volumes of CO2 generally requires pipelines that will operate above the critical pressure of CO2. Since most capture processes release CO2 at low pressure, compression of CO2 from the point of capture to pipeline will generally be required. The compression duty can be achieved using conventional multi-stage compressors or using newer shockwave type compressors. ...

Fluids have been around us for as long as we know; they have enabled us to cross the oceans, ride the winds, shorten distances, and much more. Computational Fluid Dynamics (CFD) has extended our understanding of fluids. Even to this day, the analytical solution of fundamental equations of fluid mechanics remains a million-dollar award problem (Clay Mathematics Institute). As engineers, we’ll leave ...

Prolonged 'cold' exposure poses numerous challenges for industrial operations, human survival, and living convenience. The impact of the cold cannot be quantified just based on temperatures; however, other factors such as wind speed, humidity, and irradiance have to be considered. Therefore, efforts have been made to develop combined indices, such as wind chill temperature (WCT), AccuWeather RealFeel® ...

A convergent numerical method for α -dissipative solutions of the Hunter–Saxton equation is derived. The method is based on applying a tailor-made projection operator to the initial data, and then solving exactly using the generalized method of characteristics. The projection step is the only step that introduces any approximation error. It is therefore crucial that its design ensures not only a ...

This paper proposes a data processing scheme for laser spot thermography (LST) applied for nondestructive testing (NDT) of composite laminates. The LST involves recording multiple thermographic sequences, resulting in large amounts of data that have to be processed cumulatively to evaluate the diagnostic information. This paper demonstrates a new data processing scheme based on parameterization and ...

Developing a sensitive and effective instrument for detecting the presence of red dye in diesel fuel is very advantageous for governments in preventing tax loss by controlling illegal use of the diesel fuel. The objective of this work has been to investigate and develop an instrument to detect red dye in diesel, based on the principle of absorption. The peaks of absorption in red and pure diesel ...

Pollution by micro-plastic in ecosystems is one of the major problems we are facing now, especially in marine environment. Many studies are going on the detection of different micro substances that pollute our environment. Micro-plastics are among the more frequent pollutants of the sort in aquatic ecosystems. There have been some studies earlier on methodologies to detect and identify micro-plastic ...

The literature of higher education has shown that formative peer assessment (FPA) promotes students’ learning across disciplines (Topping, 1998, Lynch et al. 2012, Li et al. 2019, among others). Despite the solid reported benefits, studies on an effective implementation of FPA are still limited in the literature (Nicol, Thomson, and Breslin 2014, Wanner and Palmer, 2018). A debilitating factor ...
