Smaller size of the filaments limits the structural support ability of the protective cage while large sizes of the filaments decreases the hydrodynamic properties of the design while increasing the pressure. The size of the filament thickness is however subject to change based on computational test results. The number of filaments is proposed to be five, not the same as the number of impeller blades, in order to shun resonance and vibration of the system. The protective cage offers protection to the vessel from the rotating components through its radial arrangements of the filaments. The elliptical design of the protective cage of filaments not only presents hydrodynamic characteristics but also provides space efficiency.
The angle designs of the blades helps in space conservation given that a number of the blades can be fitted within the pump for maximum functionality. This helps in minimizing the size of the pump to ensure it properly fits within the blood vessel. The pump is characterised with diffuser blades, which are located on the protective filament cage. A shift in the flow directionality aids the diffuser blades to convert the rotational force produced by the impellor to potential energy. A motor-magnetic bearing suspension is used to induce the pump rotation. The proposed design will aim to achieve this through the levitation and rotation of the impellor within the protective filament cage (Throckmorton et al., 2010).
The protective cage of filaments is designed with five elliptically shaped filaments. The proposal aims at modifying the design to serve both protective and design functions at the same time. The shape of the protective cage filaments serves significant role in stabilizing the impeller blades radially and axially in addition to acting as a barrier in the protection of the vessel from the rotating impeller blades. The unique elliptical design shape of the filaments plays a vital role in maximizing energy production from impeller while

The heart has four chambers, four valves and blood vessels which are joined. These chambers and valves are the main elements of the heart system. The four chambers perform different functions. Normally, these valves allow blood flow in one direction. If there is a deviation from the normal blood flow through the heart, as in the instance of a congested heart failure, a viral attack on the heart, extremely high blood pressure, disrupting the heart’s rhythm, a heart attack, malfunctioning of the valve or other heart related issues, which is often the result of a diseased heart.
Cage was born into an Episcopalian family and since his paternal grandfather regarded the violin as the “instrument of the devil”, and Cage himself first planned to become a minister, and later a writer, it was not expected that he would become a composer.
It was also performed to explore the principles governing ALDs, as well as to elucidate the steps for its construction. The results showed that ALD was an effective adjunct to liver transplantation, and can be used as a temporary replacement for damaged livers while awaiting transplantation.
Bioprosthetic valves made from bovine and porcine tissue has also been implanted in numerous patients. Both types have their indications and unique complications. This essay discusses the various types of mechanical and bioprosthetic valves, their complications, advantages and indications.
Product requirement is that it is a light weight product which is reliable and efficient. Corporate social responsibility is also a very important factor here as per which noise pollution needs to be avoided the maximum they can and also less vibrations are required.
i have known a few more things that I never thought about mechanical engineers.one fact that I always had in regards to all engineering fields is that most of the time, the engineer works indoor as opposed to
This paper examines the field of mechanical engineering, and this is mostly because of my interest in pursuing this field. It is important to understand that mechanical engineering is one of the oldest fields of technological innovations to exist. Mechanical engineering refers to a branch of engineering.
