Project Design Constraints - Research Paper ExampleGiven the design requirements of flow chambers of the heart, the material elect for the design of the heart flow chambers has to meet a load of requirements. For instance, alumina as a biomaterial, has to sustain high fluid resistance. Additionally, it has to be economical, and obviate stiffening. The material also has to fuddle good thermal conductivity. The fact that the human body happens to be one of the greatest corrosive surroundings for foreign materials style that the material used to make the flow chambers have to be able to sustain the corrosion from the active enzymes, at the human body temperature. Additionally, watchfulness has to be reserved to guarantee that the material used is not poisonous to the human body. A composite design is proposed in which the porous synthetic grafts are improved in terms of biocompatibility. Polyester textile can be coated using cross-linked protein. Studies of different kinds of prote ins such as collagen, gelatin, elastin, and albumin have been conducted. There is no ideal material yet, to use in making of prosthetic heart valves. This is because the different available materials like titanium, or stainless steel, polyester, alumina, or pyrolitic carbon have faults in one way or another. When each one of them is used by itself, the patient has to go through long anticoagulant therapy. An example of a design that can be used is the asymmetric design of the natural human heart coined by Gianni Pedrizetti and Vukicevic of Trieste University.
