Objectives: Recently, the area of Enterprise Risk Management (ERM) has received considerable attention both from the academic and professional communities. The empirical evidence seems to support the enabling role of the ERM in improving firms’ ope

The current research studies the coupled combustion inside the furnace and the steam generation inside the radiant and convection tubes through a typical Once-Through Steam Generator (OTSG). A 3-D CFD model coupling the combustion and the two-phase f

The effect of friction on nonlinear dynamics and vibration of total knee arthroplasties is yet to be investigated and understood. This research work aims at studying the influence of friction on nonlinear dynamics, friction-induced vibration, and dam

In soft and conformal contacts, the assumptions made in the Hertz theory are violated to some extent, leading to inaccurate outcomes. An alternative contact approach is the Kelvin-Voigt model that suffers from a discontinuity existing in its constitu

A new approach of coupling multibody dynamics and fluid dynamics is developed to model hydrodynamic lubrication of spherical clearance joints with thin fluid film and relative multidirectional motion. The model accounts for dynamics motion of articul

Trauma and arthritis can severely impair hip joint function resulting in pain and restricted motion. Often, affected hip joints are replaced by artificial joints which are assumed to be one of the best clinical treatment options. Presently, over one

This paper presents an in-depth numerical analysis on the hydrodynamics of a bubble column. As in previous works on the subject, the focus here is on three important parameters characterizing the flow: interfacial forces, turbulence and inlet superfi

In order to optimize and design new bubbly flow reactors, it is necessary to predict the bubble behavior and properties with respect to the time and location. In gas-liquid flows, it is easily observed that the bubble sizes may vary widely. The bubbl
