    Parametric Analysis of a Turbojet engine with reduced inlet pressure to the compressor Ujam, A.J. of desired thrust range. A flow control mechanism that produces a pressure drop across inlet was assumed and The core stream is the same as that of a turbojet and provides the hot thrust; however, the core. AOE Homework 2 One problem from this homework (to be chosen at random) will be graded for 70% of the credit on this homework. The three remaining questions will be graded for completeness only, with each worth 10%. Students must prepare their homework solutions individually, except as noted below for the ‘recitation problem’. The honorFile Size: KB.

    bubbly flow of Diesel and CNG inside a horizontal pipe. CNG’s bubbly flow behavior inside diesel exists in order to have an extensive variety of characteristics of two-phase flow (size and shape of bubbles, gas velocity, and gas area fraction). For this purpose, an analysis was executed over the bubbles of CNG inside laminar Diesel : H. A. Abdul Wahhab, A. R. A. Aziz, H. Al Kayiem, M. S. Nasif. Gas-liquid flow commonly occurs in oil and gas production and processing system. Large diameter vertical pipes can reduce pressure drops and so minimize operating costs. However, there is a need for research on two-phase flow in large diameter pipes to provide confidence to designers of equipments such as deep water risers. In this study a number of experimental campaigns were carried out to.

The experimental evaluation of a gas turbine engine's performance requires the accurate measurement of the inlet air mass flow rate into the engine. A bell-mouth engine inlet can be used for this purpose in the static test of an engine. The freestream velocity V 0 is assumed to be zero, and the flow through the bell mouth is assumed to be adiabatic and reversible.

Hot gas ingestion, the entrainment of heated engine exhaust into the inlet flow field, is the key development issue for advanced short takeoff and vertical landing aircraft.

A percent scale short takeoff and vertical landing (STOVL) hot gas ingestion model was designed and built by McDonnell Douglas Corporation (MCAIR) and tested in the. HOT GAS INGESTION CHARACTERISTICS AND FLOW VISUALIZATION OF A VECTORED THRUST STOVL CONCEPT Albert L.

Hot gas ingestion problems for STOVL (Short Take-Off, Vertical Landing) aircraft are typically approached with empirical methods and experience.

In this study, the hot gas environment around a STOVL aircraft was modeled as multiple jets in crossflow with inlet suction. The flow fieldFile Size: 7MB.

Hot gas ingestion (HGI) can be a problematic feature of short take-off vertical landing (STOVL) aircraft during the descent phase of landing, or while on the ground.

The ingress of hot gas through the rim seal of a gas turbine depends on the pressure difference between the mainstream flow in the turbine annulus and that in the wheel-space radially inward of.

Fluid flow visualization is a technique to actually see the flow patterns and get an insight in the possible theory to be applied. To see is to believe, it's said, hence this technique is very effective in understanding of fluid flow phenomena.

As the gas spirals in, it becomes hot and emits light or even X-radiation. to the mean free path of the gas molecules involved. The supersonic flow adjusts to the presence of the body by means of such shock waves, whereas subsonic flow can adjust by gradual changes in flow properties.

Shocks may also occur in the flow of a compressible medium through nozzles or ducts and thus may have a decisive effect on these flows.
