DYNAMIC SUBGRID-SCALE MODEL CONSTANT-VALUE ESTIMATION REFINED BY VECTOR-LEVEL IDENTITY IN AN ATMOSPHERIC FLOW FIELD

Dynamic subgrid-scale model constant-value estimation refined by vector-level identity in an atmospheric flow field

This study investigates the accuracy of dynamic models in predicting model constants within inviscid flow fields, such as those used in wind farm flow analysis, from the perspectives of identity and turbulent energy conservation accuracy.Specifically, results are compared between tensor-level and vector-level identities, the latter of which include

Correlation between the Porosity and Permeability of a Polymer Filter Fabricated via CO2-Assisted Polymer Compression

A porous filter was fabricated by plasticizing polymer fibers with CO2, followed by pressing and adhering; then, its gas permeability, a basic physical property of filters, was measured using N2.The as-obtained filter was well compressed and expected to approximate a sintered porous material.Therefore, the fabricated filter was analyzed by applying

Partial Single Stage Exchange Arthroplasty With Retention of a Well Fixed Cemented Femoral Stem for the Treatment of Culture Negative Infection in a Bipolar Hemiarthroplasty: A Case Report

Background: Prosthetic joint infection (PJI) is the second most common cause for revision following hip hemiarthroplasty (HHA) resulting in a mortality rate of 5.6%.The treatment of PJI is both challenging and controversial, without general consensus on best practice.In an attempt to avoid surgery, patients are commonly here prescribed antibiotics,
