This study is aimed at improving the operational efficiency of the MMZ D-245.9 diesel engine by enhancing its turbocharging system. The study focuses on the TKR 6.1 centrifugal compressor, which has been modified to incorporate an adjustable inlet guide vane assembly developed based on Patent RU2293220C2. The research...
This study investigates experimentally effects of compression ratio (CR) on the combustion, energy, and exergy characteristics of a diesel engine. A four-stroke, naturally aspirated, water-cooled, direct-injection, single-cylinder diesel engine with variable CR capacity was employed. Experiments were conducted at a con...
This study presents a comprehensive energy analysis of the Ihovbor Gas Power Plant in Nigeria, evaluating its performance in both simple cycle and steam-injected gas turbine (STIG) configurations. The research focuses on quantifying improvements in power output and thermal efficiency. Results indicate that retrofitting...
The hub ratio of a bulb turbine has an important influence on the unit’s flow capacity, efficiency, and operating stability and is one of the key parameters governing the hydraulic performance and structural safety of the turbine. To select the optimal hub ratio matching the bulb turbine of a hydropower station after l...
The growing need for sustainable energy systems has increased research interest in energy systems capable of providing power and cooling from renewable energy resources. In this regard, a geothermal-assisted ejector refrigeration cycle (PERC) is developed and thermodynamically analyzed using five different working flui...
