The TICTOP nozzle: a new nozzle contouring concept
CEAS Space Journal, 2016Currently, mainly two types of nozzle contouring methods are applied in space propulsion: the truncated ideal contour (TIC) and the thrust-optimized parabola (TOP). This article presents a new nozzle contouring method called TICTOP, combining elements of TIC and TOP design.

The Effect of Nozzles and Nozzle Loadings on Shell Buckling
Volume 3: Design and Analysis, 2015This paper investigates the effect of nozzles and nozzle loadings on the overall buckling capacity of a vessel subject to external pressure designed to ASME VIII Div 1. ASME VIII Div 1 provides a well-established design-by-rule (DBR) approach for vessels subject to external pressure, but this takes no consideration for the presence of ...

Symposium (International) on Combustion, 1963
No definitive experimental work has been done with condensation via homogeneous nucleation and very little work apparently has been done with condensation in nozzle flow, where the complications of a dynamic system are added. A review is given of the theories of homogeneous nucleation and of growth during condensation from the vapor phase.

Design of Wind Nozzle for Nozzle Augmented Wind Turbine
Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2022In some countries, wind turbines are designed to operate at relatively high speeds to be appropriately efficient, limiting the use of wind turbines in urban areas with low wind speeds. Thus, innovation is needed to enhance the possibility of wind energy use within the range of low speeds.

Nozzles: Nozzle-less Devices Defined
Journal of the American Rocket Society, 1945This is a complicated, but exact way of saying that any channel (converge n t divergent, straight or convergentdivergent) through which fluids expand to convert their heat or pressure energy into velocity in a given direction is a nozzle. Since the mass of gas is given a velocity at the expense of its heat or pressure energy, it is seen that the heat ...

Truncated Perfect Nozzles in Optimum Nozzle Design
ARS Journal, 1961A graphical technique for selecting optimum nozzle contours from a family of truncated perfect nozzles is presented which permits simultaneous consideration of various types of optima. This procedure includes the effects of friction, as well as the thermodynamic properties of the reacting gas.

A polytropic analytical equation system for the internal e ow of nozzles and ducts has been developed by a solution to the combined friction/area change compressible e ow equations. Validation of the system is sought through comparison with experimental data and numerical simulations using FLUENT in the prediction of the performances of two ...

Meniscus-confined electrodeposition (MCED) is a solution-based, room temperature process for 3D printing of metals at micro/nanoscale. In this process, a meniscus (liquid bridge or capillary) between a nozzle and a substrate governs the localized ...
