Entropy Generation Analysis due to Permeable Exponential Stretching in Boundary Layer Flows

Heat Transfer, EarlyView.
ABSTRACT Entropy generation represents the irreversible loss of useful energy in thermal–fluid systems, directly reducing efficiency in applications, such as microelectronics cooling, nanofluid‐based heat exchangers, and polymer processing. This study investigates entropy generation in a two‐phase viscoelastic nanofluid flow over a permeable ...

Reallocation of active lithium by regulating electrochemical structural connectivity in anode‐free lithium metal batteries

InfoMat, EarlyView.
The columnar Li stacks induced by high‐density spatial multidimensional nucleation mode have stable bulk‐phase electronic pathway and interfacial kinetic structure, which significantly reduces the quasi‐linear accumulation of irreversible Li during the cycling process.

Energy Partitioning Constraints at Kinetic Scales in Low- Turbulence [PDF]

Turbulence is a fundamental physical process through which energy injected into a system at large scales cascades to smaller scales. In collisionless plasmas, turbulence provides a critical mechanism for dissipating electromagnetic energy.

4D Flow MRI Velocity and Turbulence Mapping in Mild Valvular Heart Disease

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Valvular heart disease (VHD) commonly leads to the development of turbulent blood flow. Turbulent kinetic energy (TKE), measured with 4D flow MRI, may be a complement to current metrics for early identification of VHD. Purpose To investigate TKE as a marker of VHD in relation to flow velocity and cardiovascular geometry.

Computation of turbulent boundary layer flows with an algebraic stress turbulence model [PDF]

An algebraic stress turbulence model is presented, characterized by the following: (1) the eddy viscosity expression is derived from the Reynolds stress turbulence model; (2) the turbulent kinetic energy dissipation rate equation is improved by including

Alcohol Septal Ablation in Hypertrophic Obstructive Cardiomyopathy: Long‐Term Follow‐Up of Deformations and Hemodynamics

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background A detailed evaluation of hemodynamics, supportive morphology, and deformation may help uncover the pathophysiology of hypertrophic obstructive cardiomyopathy (HOCM) and the changes wrought by alcohol septal ablation (ASA). Purpose To investigate the global cardiac volume, myocardial deformation, and hemodynamic characteristics ...
