Equation for ( k = \frac12 \overlineu_i' u_i' ): Multiply RANS for ( u_i' ) by ( u_i' ) and average. Result: [ \frac\partial k\partial t + \baru j \frac\partial k\partial x_j = \underbrace-\overlineu_i' u_j' \frac\partial \baru i\partial x_j \textProduction \mathcalP \underbrace- \nu \overline\frac\partial u_i'\partial x_j \frac\partial u_i'\partial x_j \textDissipation \varepsilon
