Hybrid Power Generation System Through Vertical Axis Wind Turbine And Solar Pv, Zeeshan Memon Aug 2021

Hybrid Power Generation System Through Vertical Axis Wind Turbine And Solar Pv, Zeeshan Memon

English Language Institute

The design of a hybrid electric power generation system utilizing both wind and solar energy for remote area is today’s need. The system has two basic components – one for generation of electricity through Solar Energy and another one for generation from Wind Energy. Even in the case of absence of either of the two sources, the other remaining source could be used to supplement the absence of the former. The power from wind current can be extracted using a vertical axis turbine. Vertical axis turbine is capable of extracting power form wind regardless of the direction of flow. The …


Gases Concept Inventory (Gci): An Instrument Test To Analyze Students’ Mental Models Of The Kinetic Theory Of Gases, Muhammad Guntur Purwanto Aug 2021

Gases Concept Inventory (Gci): An Instrument Test To Analyze Students’ Mental Models Of The Kinetic Theory Of Gases, Muhammad Guntur Purwanto

English Language Institute

This poster is to promote a Gases Concept Inventory (GCI) as an instrument test to evaluate students’ mental models on kinetic theory of gases. By evaluating mental models using GCI, teachers can assess students’ initial perception and understanding in kinetic theory of gases, so they can prepare the best method to deliver kinetic theory of gases concept to students. THE GCI is analyzed by evaluating its validity, reliability, and difficulty level to prove that GCI is valid and reliable to be used.


Solar Thermal Cooling System: A Feasible Option For The Maldives, Ahmed Fathhee Aug 2021

Solar Thermal Cooling System: A Feasible Option For The Maldives, Ahmed Fathhee

English Language Institute

This poster presents the potentiality of utilizing solar and converting thermal energy to cool buildings in the Maldives. A thermal model of a typical building showing the annual cooling load is presented which was used to run a simulation model of a solar thermal cooling system. Simulation data shows that it is possible to use a solar thermal cooling system to cool the buildings effectively.


Types Of Oil Recovery Methods To Increase Oil Productions, Astrid Rodriguez Aug 2021

Types Of Oil Recovery Methods To Increase Oil Productions, Astrid Rodriguez

English Language Institute

In the oil industry, different recovery methods are applied to produce a percentage of the hydrocarbon storage in a reservoir. These methods are classified into three principal categories: primary, secondary, and tertiary recovery. Their selection and implementation depend on the reservoir and fluids properties. According to the recovery method selected, it is possible to recover different quantities of hydrocarbon.


Potential Energy Generation From Agricultural Residue In Indonesia, Adrian Rizqi Irhamna Aug 2020

Potential Energy Generation From Agricultural Residue In Indonesia, Adrian Rizqi Irhamna

English Language Institute

Indonesia has great potential of biomass sources from their agricultural residue, which can potentially be used for alternative energy generation. This preliminary research explores the most suitable technology for energy generation from agricultural residue and its challenge for application in Indonesia. The study showed that biomass utilization via the direct combustion process is recommended for energy generation. It is also reported that the pretreatment process of drying and washing, are required to increase the fuel quality and plant efficiency.


Applying Renewable Energies Against Climate Change: Solar Photovoltaic (Pv) Energy, Juan Jose Estribi Aug 2020

Applying Renewable Energies Against Climate Change: Solar Photovoltaic (Pv) Energy, Juan Jose Estribi

English Language Institute

In recent years, more efforts towards fighting climate change have been done. As a direct response, research and technology have offered several insights regarding the specific causes, effects, and even possible solutions for resolving this global issue. Among these solutions, renewable energies and their potential contributions as clean energy sources can be assessed as feasible options for the energy transformation through the decarbonization process of the energy industry. This poster is mainly focused on solar photovoltaic (PV) energy and its great potential as a renewable energy by making a brief assessment of some important aspects such as resource availability, its …
