The present invention relates to a turbine arrangement driven by exhaust gases from a combustion engine. The turbine arrangement comprises a turbine housing, a turbine wheel rotatably arranged in the turbine housing, a first volute section defining a curved flow passage extending about 360&#xb0; around the periphery of the turbine wheel, and an inner radial passage directing exhaust gases radially inwardly from the flow passage into a swept area of the turbine wheel. The curved flow passage has a cross section area decreasing continuously in the flow direction of the exhaust gases from an initial area at an initial angular position of the curved flow passage to an end angular position. The flow area decreases continuously with a successively reduced value from the initial angular position to an angular position located at least 270&#xb0; from the initial angular position.
