How to solve heat transfer problems
WebUsing explicit finite difference we need to extend the interval to 160+1.6 cm and 160+3.2 if we choose 16 mm as our differential length. The initial condition for the extended interval should be 298K and the boundary condition for all time it is at 298 K.Am I right? @user1318499 – user471651 Feb 19, 2024 at 3:39 WebThen we’ll consider problems with zero initial conditions but non-zero boundary values. We can add these two kinds of solutions together to get solutions of general problems, where …
