FLIGHT LIMITATIONS IMPOSED ON SINGLE ROTOR AND COAXIAL HELICOPTERS BY THE LIFT EQUATION

期刊: ANZIAM JOURNAL, 2023; 65 (1-2)

To compute the maximum speed threshold for helicopters, we model the lift produced by the rotor blades. Using this model, we derive limits for each me......

NUMERICAL ANALYSIS OF APPARATUS-INDUCED DISPERSION FOR DENSITY-DEPENDENT SOLUTE TRANSPORT IN POROUS MEDIA

期刊: ANZIAM JOURNAL, 2023; 65 (1-2)

The effects of apparatus-induced dispersion on nonuniform, density-dependent flow in a cylindrical soil column were investigated using a finite-elemen......

COUETTE FLOW OVER A HEAT ISLAND

期刊: ANZIAM JOURNAL, 2023; 65 (1-2)

A viscous fluid is confined between two smooth horizontal walls, in a vertical channel. The upper wall may move with constant speed, but the lower wal......

MODELLING MICROWAVES IN BAUXITE

期刊: ANZIAM JOURNAL, 2023; 65 (1-2)

Sending microwaves through bauxite ore allows almost continuous measurement of moisture content during offload by conveyor belt from a ship. Data and ......

WALL STABILIZATION IN MINES BY SPRAY-ON LINERS

期刊: ANZIAM JOURNAL, 2023; 65 (1-2)

Thin spray-on liners (TSLs) have been found to be effective for structurally supporting the walls of mining tunnels and thus reducing the occurrence o......

THE METRIC OPERATORS FOR PSEUDO-HERMITIAN HAMILTONIAN

期刊: ANZIAM JOURNAL, 2023; ()

The Hamiltonian of a conventional quantum system is Hermitian, which ensures real spectra of the Hamiltonian and unitary evolution of the system. Howe......

AN EXAMINATION OF THE LANIER WING DESIGN

期刊: ANZIAM JOURNAL, 2023; 65 (1-2)

Six patents were secured by E. H. Lanier from 1930 to 1933 for aeroplane designs that were intended to be exceptionally stable. A feature of five of t......

ON THE SAFE STORAGE OF BAGASSE

期刊: ANZIAM JOURNAL, 2023; 65 (1-2)

In this paper, we investigate the thermal evolution in a one-dimensional bagasse stockpile. The mathematical model involves four unknowns: the tempera......

DOUBLE LAYERED COMPRESSIBLE MASKS

期刊: ANZIAM JOURNAL, 2023; 65 (1-2)

Double-masking may be used to reduce the transmission of a virus. If additionally the masks are compressible, with different permeabilities and behavi......

BURSTING SOLUTIONS OF THE RÖSSLER EQUATIONS

期刊: ANZIAM JOURNAL, 2023; 65 (1-2)

We provide an analytic solution of the Rossler equations based on the asymptotic limit $c\to \infty $ and we show in this limit that the solution take......
