The advisability of using combustion chambers with a toroidal recirculation-mixing zone in small-sized gas turbine engines

MATEC Web of Conferences, 2018
The interrelations between the size of the gas turbine engine (GTE) and the size and workflow of the combustion chamber (CC) were considered. On the base of analysis of workflow organization the design of CC with toroidal recirculation mixing zone was ...

Mathematical model of bent-flattened sintered-grooved heat pipe with concept of receding-and-excessing fluid

Case Studies in Thermal Engineering, 2021
A mathematical model that uses the concept of evaporation and condensation to explain the process of heat and mass transfer within the bent, flattened heat pipe has been established to predict its wall temperature and thermal resistance.

Area targeting and storage temperature selection for heat recovery loops [PDF]

, 2012
Inter-plant heat integration across a large site can be achieved using a Heat Recovery Loop (HRL). In this paper the relationship between HRL storage temperatures, heating and cooling utility savings (heat recovery) and total HRL exchanger area is ...

Detection of Gate Valve Leaks through the Analysis Fractal Characteristics of Acoustic Signal

Fractal and Fractional
This paper considers the possibility of using monofractal and multifractal analysis of acoustic signals to detect water leaks through gate valves. Detrended fluctuation analysis (DFA) and multifractal detrended fluctuation analysis (MF-DFA) were used ...

Durable Response to Maintenance Treatment Comprised of Viagenpumatucel-L, Nivolumab, Ramucirumab, and Docetaxel in a PD-L1-Low Advanced-Stage Non-Small-Cell Lung Cancer: A Case Report

Case Reports in Oncology, 2023
Checkpoint inhibitors (CIs) are now standard of care for late-stage non-small-cell lung cancer (NSCLC); however, only a minority of patients treated with a CI show clinical benefit compared to platinum-based chemotherapy alone, regardless of programmed ...
