Energy and exergy analysis of an organic Rankine-Brayton combined cycle
Kaşka, Önder; Bor, Onur; Tokgöz, Nehir (GAZI UNIV, 2018)In this study, thermodynamic analysis of reheat and intercooled Brayton cycle combined with organic Rankine cycle (ORC) using waste heat from intercooler in Brayton cycle as heat source is presented. The effects of different ... -
Experimental investigation of flow characteristics of corrugated channel flowusing PIV
Tokgöz, Nehir; Aksoy, Muhammed Murat; Şahin, Beşir (YILDIZ TECHNICAL UNIV, 2016)The aim of the study is to determine the flow characteristics of corrugated duct. The whole study has been conducted for Reynolds numbers, Re=4000 and 6000. The corrugated duct geometry was designed for aspect ratios, ... -
First and second law evaluation of combined brayton-organic rankine power cycle
Kaşka, Önder; Bor, Onur; Tokgöz, Nehir; Aksoy, Muhammed Murat (YILDIZ TECHNICAL UNIV., 2020)In the present work, we have conducted thermodynamic analysis of an organic Rankine cycle (ORC) using waste heat from intercooler and regenerator in Brayton cycle with intercooling, reheating, and regeneration (BCIRR). ... -
Optimization of the pool boiling heat transfer in the region of the Isolated bubbles using the ABC algorithm
Alic, E.; Çermik, O.; Tokgöz, Nehir; Tokgöz, Nehir (ISFAHAN UNIV TECHNOLOGY, 2019)The region of the isolated bubble regime, in which the bubbling starts, is a very significant process for boiling heat transfer. In this study, Artificial Bee Colony algorithm (ABC), which is mainly based on the searching ... -
The numerical study of heat transfer enhancement using Al2O3-water nanofluid in corrugated duct application
Tokgöz, Nehir; Alıç, E.; Kaşka, Önder; Aksot, M. M. (Yildiz Technical University, 2018)Heat transfer enhancement in channel flow is investigated in the present study by using corrugated duct in lieu of smooth duct. In this regard, periodic different cavities are applied on the duct walls using the same aspect ...
