Data in Brief, 2022 : The modelling of turbulence for IC engine applications is quite a challenging task. Large Eddy Simulation (LES) is the best approach to model the turbulence as the flow is three dimensional, chaotic, transient, diffusive, dissipative and intermittent ...

Numerical Simulation of Bubble Growth in Liquid Jet Impingement on a Hot Plate
Journal of Thermal Science and Technology, 2012 Complete numerical simulations are performed for bubble growth in water jet impingement on a hot plate. The governing equations for the conservation of mass, momentum and energy are numerically solved in the liquid, vapor and air phases. The liquid-vapor

Does Climate Change Risk Impact Insurance Credit Risk? Cross Country Evidence
Business Strategy and the Environment, EarlyView.ABSTRACT While climate change poses a significant financial risk to the insurance industry, research has not yet examined the impact on the insurer's credit risk. This study investigates the impact of climate change risks on credit risk for insurance firms.

Modelling the dynamics of turbulent floods [PDF]
arXiv, 1999 Consider the dynamics of turbulent flow in rivers, estuaries and floods. Based on the widely used k-epsilon model for turbulence, we use the techniques of centre manifold theory to derive dynamical models for the evolution of the water depth and of vertically averaged flow velocity and turbulent parameters. This new model for the shallow water dynamics

Business Strategy and the Environment, EarlyView.ABSTRACT This study examined how Bitcoin, energy prices, and geopolitical risk interact by examining the first four moments (mean, variance, skewness, and kurtosis) of their return distributions by using wavelet analysis. The findings reveal that the co‐movement patterns of energy index, geopolitical risk index, and Bitcoin prices are time and ...

Analysis of an RNG based turbulence model for separated flows [PDF]
A two-equation turbulence model of the K-epsilon type was recently derived by using Renormalization Group (RNG) methods. It was later reported that this RNG based model yields substantially better predictions than the standard K-epsilon model for ...

Biotechnology Progress, EarlyView.Abstract One strategy to enhance the production of biological therapeutics is using transient perfusion in the preculture (N‐1 stage) to seed the production culture (N stage) at ultra‐high cell densities (>10 x 106 viable cells/mL). This very high seeding density improves cell culture performance by shortening the timeline and/or achieving higher final

Validation of a new k-epsilon model with the pressure diffusion effects in separated flows [PDF]
arXiv, 2007 The contribution of the "rapid" part of the pressure diffusion to the turbulent kinetic energy balance is analyzed, and a new model to describe its effect is suggested. A new transport equation for the turbulent kinetic energy is derived. The new k-equation does not require any modification in the standard epsilon-equation. A new k-epsilon model, which
