Enhancement Of Gas Turbine Efficiency By Using Recuperator And Intercooler Systems, Mohammed Saad Kamil Jun 2026

Enhancement Of Gas Turbine Efficiency By Using Recuperator And Intercooler Systems, Mohammed Saad Kamil

Al-Esraa University College Journal for Engineering Sciences

High power density and operational flexibility make gas turbines an indispensable part of contemporary energy conversion systems. However, in the simple cycle configuration, the thermal efficiency is generally low because the exhaust heat loss is large and the compression work is high. The current investigation is focused on enhancing the thermal efficiency of a gas turbine by the introduction of two augmentation schemes, namely a recuperator and an intercooler. A numerical and thermal simulation study was carried out to model the gas turbine cycle based on the first and second laws of thermodynamics. Simplicity and Modified cycles Performance of simple …

Ai-Enhanced Heat Transfer Optimization In Magnetic Bio-Nanofluids, Hasan Attyah Shaboot Jun 2026

Ai-Enhanced Heat Transfer Optimization In Magnetic Bio-Nanofluids, Hasan Attyah Shaboot

Al-Esraa University College Journal for Engineering Sciences

This study presents a hybrid Artificial Intelligence–Computational Fluid Dynamics (AI-CFD) framework for optimizing heat transfer in magnetic bio-nanofluids subjected to external magnetic fields. Magnetic bio-nanofluids, composed of biocompatible base fluids containing superparamagnetic nanoparticles, exhibit tunable thermal and flow behavior, making them promising for biomedical and micro-cooling applications. Conventional optimization methods based on experiments or brute-force CFD are computationally expensive and limited in exploring the full design space. To overcome these challenges, an Artificial Neural Network (ANN) surrogate model was developed to predict two key performance indicators, the Nusselt number and the friction factor, with high accuracy (R2 > 0.997).

Effect Of High Protein Diets On Kidney Health Among Athletes And Bodybuilders With Normal Kidney Function, Mustafa Mehdi Alqazzaz, Sajad Abdullah Jleep, Nouran Hussein Mutlaq, Ali Jabbar Jassem

Al-Esraa University College Journal for Medical Sciences

This study emphasizes the effect of high-protein diets(HPD) on kidney function, focusing on key biomarkers (Albumin, Urea, Creatinine & GFR). A HPD is defined as a protein consumption >1.5g/kg per day. Results indicated variations in certain biomarkers among the participants (healthy athletes & bodybuilders with normal kidney function) suggesting potential changes in renal workload. Many studies in resistance-trained athletes focusing at HPD, concluded that there are no harmful effects of HPD on renal health. While no immediate kidney damage was observed, we suggest further investigation into the long -term implications of HPD, particularly for individuals with specific health conditions.

Evaluation Of A Vortex Flow Device On A Center Pivot Irrigation System, Ankit Chandra, Derek M. Heeren, Tyler Smith

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

This study presents the first independent field evaluation of a passive vortex flow device designed to reduce hydraulic friction in pressurized irrigation systems. Experiments were conducted on a full-scale, groundwater-fed center pivot irrigation system at the Eastern Nebraska Research, Extension, and Education Center (ENREEC). A paired comparison approach was used to quantify differences in flow rate, energy consumption, and pressure distribution along the pivot lateral under baseline (no device) and treatment (device installed) conditions. Results showed negligible change in system flow rate (621 vs. 618 gpm) and energy consumption (~1.2% difference), consistent with expectations for pressure-regulated irrigation systems. However, the …
