- Right now all across the globe, scientists, engineers, technicians, and hardworking students are trying to calculate a heat transfer problem for their work or class. Fortunately, the "Heat Transfer Free" app comes to the rescue. It is an elegant and powerful tool for calculating steady state heat transfer phenomena via conduction, convection, and radiation.

- The app incorporates all possible types of convection such as pure convection (no conduction), single convection (conduction with one-sided convection), and double convection (conduction with convection on both sides).

- It calculates radiation emission for various configurations of arbitrary emissivity such as the heat transfer emitted by a grey body, a grey body embedded in an environment, or two grey bodies.

- The app is also equipped with a heat transfer calculation of uniform cross sectional fins under various boundary conditions such as fins with free or insulated ends, and fins with specified temperature at end.

- A graphical representation of temperature distributions is shown, through elegant and clear plots.

- There is a substantial number of figures, in order to make "Heat Transfer Free" an engaging, unique, and most of all simple application. A valuable tool for everyone who is interested in heat transfer phenomena.
