Introduction The focus of this assignment is to study flow characteristics in the transition regime in converging diverging nozzles using fluent. GAMBIT was used to create the mesh geometry. Solidworks CAD software was used to create the geometry. The Study will also describe the method used for simulating flows and the specific geometry and flow conditions. Fluent has been used to model the fluid flow in a convergent-divergent nozzle. Literature review For this assignment, compressible flow ...
Introduction: Short increment sensitivity index test . A hearing test used to determine differential sensitivity to changes in loudness. This test is based on a phenomenon known as recruitment (abnormal loudness growth). It was Dix and Hallpike who related th presence of loudness recrutiment to cochlear pathology. Difference limen for intensity (DLI): is the smallest change in the intensity of a pure tone which can just be detected. It is usual for patients with normal hearing to have difficu...
Soldering is a method where the solder is melted with low temperature in order to connect two pieces of metal. It is very different from welding and brazing process in terms of temperature since it uses much lower temperature compared to both processes. It is used widely in the electronic industry such as in manufacturing electronic devices[ ].This was one of the most important processes back then in late 1980's as it has been used to solder copper water supply pipes. A problem arose when the...
CHAPTER 2 LITERATURE REVIEW 2.1 Introduction In this excellent chapter, those things that have discussed are about the phase that use in the study. It is consists the theory of the research and the journal that discovered from the previous researches. A few of the resources to complete this analysis even get from publications, and also previous studies that make by past student. There are some examples of case studies to maximize the efficiency of aluminum alloys made by many researchers. Lit...
Currently, emissions of Nitrogen oxides (NOx), Total hydrocarbon (THC), Non-methane hydrocarbons (NMHC), Carbon monoxide (CO) and particulate matter (PM) are regulated for most vehicle types, including cars, lorries, trains, tractors and similar machinery, barges, but excluding seagoing ships and aeroplanes. For each vehicle type, different standards apply. Compliance is determined by running the engine at a standardised test cycle. Non-compliant vehicles cannot be sold in the EU, but new sta...
Abstract-A Fault-tolerant dynamic scheduler meant for grid applications that uses job replication along with combines the compensation of static scheduling, specifically no overhead for the mistake free case, and low overhead in case of a fault. The dependency arrangement of a parallel program can be described by means of a directed acyclic graph (DAG). Scheduling graph consists of ordering the jobs and mapping them to processing units. Faults can happen at any point during time. A fault can ...
Proposal for energy saving nanoparticles treatment for roof 1. Abstract Standard size house loses more than 55% of cooling energy due to solar radiation, and out of 55%, more than 45% through roof. [3] Some of the conventional roofing materials are hard to apply on surface. Some of them have high maintenance cost; some of them are required to change original color of the roof. These conditions create huge economics opportunity. Purpose of the project is to develop and design energy saving nan...
The manufacturing cost of the finished cylinder block is the most important factor in determining the selection of the manufacturing process and the material. The cost to manufacture a cylinder block is made up of the cost of material ( C1 ), the salary of the technician/operator ( C2 ) who made this block, the cost of tooling ( C3 ) ,the capitalized cost of the equipment ( C4 ) (milling machine), cost of overhead ( C5 ) and the cost of purchased component(Cylinder liners)(C6) Total Unit cost...
The landing gear, is a structure (or mechanism) attached to the fuselage (or the body) of the aircraft, helps the aircraft during landing, take-off and ground handling operations. The landing gear plays important role absorbing the crush (or thrust) while landing and thus ensure lower crush related injuries and material damages. For achieving this �crush worthiness� require optimum design of the springs of the landing gears. I have started the process of the �optimum design� of the la...
The landing gear is an important part of an aircraft as far as the take-offs and landings are concerned. The landing gear mechanisms (or structures) are pretty simple in case of the commercial helicopter as compared to the commercial airplanes. But, that is not the case for the naval helicopters. Because of the not-so-friendly landing conditions, the naval helicopter must have sophisticated landing gear mechanism connected with its fuselage. The design of the landing gear mechanism for the na...
