摘要:

AbstractTwo programs are introduced to provide flexible and portable C‐language programs for investigating design and analysis alternatives for prime‐focus paraboloidal reflectors. FeedPat enables the study of the aperture illumination provided by a particular feed. DishPat computes the resulting radiation pattern and provides graphical output. Using simple piecewise‐constant numerical integration, DishPat employs square subareas which are easy to manage and may be readily extended to handle a variety of reflector outlines as well as feed offsets. Equivalent magnetic surface currents limit the validity of the radiation to the forward half‐space, but the loss in coverage is offset by the simplicity of the code. Not only useful for learning, the programs may be readily modified into practical desig

摘要:

AbstractGood discipline‐specific projects wherein computational schemes may be applied are generally difficult to find and time‐consuming to develop. This article describes one such case study in the area of convective heat transfer involving what is known as a laminar, thermal entry‐length flow. The algorithm follows directly from first principles and is straightforward to implement, while demonstrating many of the principles of successful computational techn

摘要:

AbstractThis article emphasizes the use of interactive simulation packages as an integral part of the problem solution in both engineering education and practice. A homework problem in fluid mechanics is presented. Using numerical simulation of a tank and draining pipe arrangement, the students were required to find the effect of the viscosity of the fluid, draining pipe length, and initial fluid level in the tank on the initial draining velocity and the time required for complete draining of the tank. The results obtained were surprising and unexpected, encouraging the students to investigate further the model equations in order to find an explanation for the unexpected system behavior.

摘要:

AbstractThis article describes the use of the software packageTLINE, which includes three programs for the sinusoidal steady‐state analysis of transmission lines. The first program provides analysis of the tandem connection of several transmission lines with the possibility of includingPI, T, orLlumped‐element discontinuity junctions between the transmission lines. The other two programs are related to analysis of impedance matching using single and double stubs. All analysis procedures are graphically displayed on Smith charts. Output files that include numerical values of input impedances, values of time‐average powers, and reflection coefficients at various sections of a tandem transmission line system are included. The TLINEsoftware package is used to train students on the use of the Smith chart and also to help in the teaching and demonstration of various transmission line and impedance‐matching c
