The paper considers the results of analyzing the aerodynamics and heat exchange of a fixed cylinder under nonstationary airflow with average-velocity alternating pulsations numerically. It is shown that the pulsations significantly affect the vortex separation frequency, the Karman vortex street behind the cylinder, the pulsation frequency of the aerodynamic and heat exchange coefficients, and their average and amplitude values. The authors determined the engineering applications.
