Problem Statement
Use of renewable energy is one of major emerging issues in the world. Need of energy from
renewable sources and being stored in different forms is in the rise. Home and factors are
looking at ways to invest in zero carbon means and use of air compressor is a key move to
achieve those targets (Gopalakrishnan, Gupta & Chaudhari, 2014). This project will look at a
design of a rotary compressor which is propelled from air energy and design of a storage system
of the compressed air energy. The energy fluctuation problems are able to affect the functionality
of the compressors. The design of air compressors is able to solve this problem since air will be
compressed all through and energy availability will not be an issue anymore.
Literature Review
Compressed air which is under high or moderate pressure is used to propel the twin-screw air
compressor. The compressor has two important identical rotors which have helical grooves. The
compression process is important in generating the power to propel the compressor (Giampaolo,
2010). Due to their use of renewable energy and advantages, the crew compressors have been
widely accepted in the market. Additionally, the screw compressors are able to enjoy much high
efficiency, reliability, long service compactness and high speeds than other positive displacement
compressors. There are two key designs of air rotary compressors which include single and twin
screw air compressors (Nwauha, 2013). The functionallity76 of the screw air compressor

functions whereby air is compressed through the screw action. The compressed air is then
directed to compressed air energy storage system. This compressed air is used to generate heat.
During the expansion process, heat is usually removed from the system. The heat generated can
therefore be stored in the system or be used for expansion. The functionality of the screw
compressor acts when the pressure of the gas is raised through the reduction of the volume of the
gas. In addition, the oil injected twin screw air compressor has twin rotational screws. The oil is
fed into the gas stream in order to absorb the compression heat (Mike, 2013). The oil feeding
helps to increase the pressure ratio in the system without any intercooling ad also help in
protection of the compressor from gases which may lead to corrosion.
Scope of the Proposed Work
This project will involve modeling of the air compressor and testing its functionality. A model of
the air compressor will be developed. First, the project will involve collection of the required
material. Mathematical modeling will then follow. In addition, the design of the parts of the air
compression for the air compression will be carried out. The designs will be used for modeling a
prototype. After that, a prototype of the air compressor will be designed using the modeling
procedures. The modeling and prototyping will be common in this project to test the storage of
the air compressed energy and its used in the air compressor.
Proposed Approach
There are different approaches which can be implemented in the implementation of this project.
Some of the key available approaches include computerized designs, computational fluid
dynamics, mathematical modelling, and experimental validation. Nevertheless, due to the high
