Chapter 5 Numerical Methods in Heat Conduction τ α == × = Δ Δ t x 2 6 2 125 10 002 0 46875 (. ) . m / s)(15 s) m 2 Substituting this value of and other given quantities, the nodal temperatures after 5 × 60/15 = 20 time steps (5 min) are determined to be After 5 min: T 0 =228.9 ° C, T 1 =228.4 ° C, T 2 =226.8 ° C, T 3 =224.0 ° C, and T 4 =219.9 ° C ( b ) The time needed for transient operation to be established is determined by increasing the number of time steps until the nodal temperatures no longer change. In this case steady operation is established in ----
