Description

From the listing uploaded by “appupdater”.

Toss the gas tables out the window, forget about the interpolations and the cumbersome calculations. Download CFTK, learning gas dynamics has never been made this easy before. In this ever growing tech world, it becomes essential to utilize our resources to their maximum extent, and that is exactly what CFTK does. CFTK is developed to take the maximum advantage of your android's capabilities to provide solutions to engineering problems in mere seconds. The purpose of this app is to provide a user-friendly instantaneous gas dynamics calculator which will serve as a tool for understanding and also as a teaching aid. It includes Isentropic flow, Normal and Oblique shocks, Fanno and Rayleigh flow. A toggle switch provided allows users to switch between supersonic and subsonic flow regimes in no time! Tapping the info button provides you with information regarding the proper usage of the toolkit along with explaining the flow conditions. Now in v2.0, input fields can evaluate your math expressions (using EvalEx), providing faster precise computation. Also, not just ratios now, CFTK 2.0 allows you to calculate the absolute values on tapping the ratio text. For further information/bugs/suggestions drop a mail to [email protected]
