The initial‐value problem of a forced Burgers equation is numerically solved by the Fourier expansion method. It is found that its solutions finally reach a steady state of ‘‘laminar flow’’ which has no randomness and is stable to disturbances. Hence, strictly speaking, the so‐called Burgers turbulence is not a turbulence. A new one‐dimensional model is proposed to simulate the Navier–Stokes turbulence. A series of numerical experiments on this one‐dimensional turbulence is made and is successful in obtaining Kolmogorov’sk−5/3inertial‐range spectrum. The (one‐dimensional) Kolmogorov constant ranges from 0.5 to 0.65.
