Numerical study of an exhaust heat recovery system using corrugated tubes and twisted tape inserts [PDF]

, 2014
Thesis (M.S.) University of Alaska Fairbanks, 2014Diesel engine generators are the major power source for small communities in cold regions. Diesel generators waste about 1/3 of their fuel energy in the form of heat through exhaust gas.

Exploring Nasal Structural‐Microbial Interactions in Multiple Sclerosis‐Associated Olfactory Impairment

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Olfactory dysfunction is frequently observed in patients with multiple sclerosis (MS); however, its underlying mechanisms remain poorly understood. To date, no studies have directly examined the nasal mucosal microbiota in MS. This study aimed to explore potential relationships among olfactory function, nasal microbiota composition,

Evaluation of Alternative Designs for a High Temperature Particle-to-sCO2 Heat Exchanger

Journal of solar energy engineering, 2018
This paper presents an evaluation of alternative particle heat-exchanger designs, including moving packed-bed and fluidized-bed designs, for high-temperature heating of a solar-driven supercritical CO2 (sCO2) Brayton power cycle.

Response Surface Method for Design of Room Air Conditioner Heat Exchangers with Decreasing Tube Diameter

Zhileng xuebao, 2011
The response surface method is applied to design the heat exchanger with decreasing tube diameter, for the traditional design methods are not suitable for the optimization of the performance and cost of heat exchanger simultaneously.

The MMP‐9/TIMP‐1 Ratio and Concentrations of Osteopontin Are Elevated in Cerebrospinal Fluid of People With Multiple Sclerosis and Decrease After Autologous Hematopoietic Stem Cell Transplantation

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives To evaluate the utility of cerebrospinal fluid (CSF) biomarkers—matrix metalloproteinase‐9 (MMP‐9), tissue inhibitor of metalloproteinases‐1 (TIMP‐1), the MMP‐9/TIMP‐1 ratio, and osteopontin (OPN)—as indicators of blood–brain barrier (BBB) integrity and disease activity in people with relapsing–remitting multiple sclerosis (pwMS ...

Pengaruh Kecepatan Fluida Terhadap Nilai Efektivitas pada Heat Exchanger Tipe Shell and Tube (The Effect of Fluid Flow Velocity to Determine the Effectiveness of Heat Exchanger Shell and Tube) [PDF]

, 2016
As a device to exchange heat from hot fluid to colder fluid, a heat exchanger is supposed to have high effectiveness. Theoretically, the increase of fluid rate would increase the effectiveness.

Experimental assessment of a helical coil heat exchanger operating at subcritical and supercritical conditions in a small-scale solar organic rankine cycle [PDF]

, 2017
In this study, the performance of a helical coil heat exchanger operating at subcritical and supercritical conditions is analysed. The counter-current heat exchanger was specially designed to operate at a maximal pressure and temperature of 42 bar and ...

Using a Supramolecular Approach to Engineer Modular Hydrogel Platforms for Culturing Protoplasts – from General Tissue Engineering to Cellular Agriculture

Advanced Biology, EarlyView.
Using supramolecular monomers, various hydrogel culture systems were formulated to culture protoplasts; including 2D, 2.5D, and 3D hydrogels. Depending on the culture platform, bioactive functionalization led to protoplast enlargement (2D and 2.5D) or plasmolysis (3D). This work shows the potential to modularly engineer synthetic platforms for cellular

Preliminary Design and Analysis of Regenerative Heat Exchanger

Chemical Engineering Transactions, 2016
Heat regenerators transfer heat from one gas to another, with by storage in solids. This type of heat exchanger is used primarily when heat has to be transferred between enormous amounts of gases, when the gases are dirty and liable to plug up the ...
