DELTAE-Design Environment for Low-Amplitude ThermoAcoustic Engines-is a computer program that can predict how a given thermoacoustic apparatus will perform, or can allow the user to design an apparatus to achieve desired performance. It is currently running on IBM-compatible or Macintosh PCs, VAX minicomputers, and several types of UNIX workstations. It is substantially menu-oriented. Input data can be modified or entered via DELTAE's menu or using any text editor. Results can be examined via the menus, the operating system's text utilities, or any spreadsheet or graphics software.
For good portability, DELTAE is written in FORTRAN-77. The executable code for IBM-compatibles requires 260 kbytes of free RAM, and runs comfortably quickly on a 286 with math coprocessor, or anything more sophisticated. All calculations are performed in double precision.
