A summary of results of numerical investigations of the two-dimensional flow around a heated circular cylinder located in a laminar crossflow is presented. Numerical investigations were carried out for the Reynolds number range 10(-4) less than or equal to Re less than or equal to 200 and for temperature loadings of 1.003-1.5. The computations yield information on Nu and C-D variation with Reynolds number. The temperature dependence of the fluid properties lair) was taken into account and this resulted in a temperature dependence of the Nu-Re and C-D-Re results. Information is also provided on the Strouhal number dependence on the Re number and on the critical Re number where Vortex shedding starts.
