a plurality of plates, mutually parallel and spaced apart to form a flow channel therebetween, each plate of the plurality of plates having a plurality of corrugations, wherein at least one of the corrugations comprises an intrados wing profile shaped camber followed by an extrados wing profile shaped camber;

wherein the at least one of the corrugations includes an intrados surface and an extrados surface, the extrados surface defining an airfoil configuration;

wherein the plurality of plates include drainage grooves, orthogonal to the main gas flow direction;

wherein at least some grooves of the plurality of grooves are on the extrados surface and are further configured to increase energy of a turbulent boundary layer on the extrados surface; and

wherein the corrugations do not include sinusoidal curves and do not include curves joined by straight sections.

2. The gas liquid separator of claim 1 , wherein the corrugations comprise the extrados wing profile shaped camber followed by an intrados wing profile shaped camber.

3. The gas liquid separator of claim 1 , wherein the plurality of plates comprises multiple drainage grooves aligned orthogonal to the main gas flow direction.

4. The gas liquid separator of claim 1 , configured as a steam water separator.

5. The gas liquid separator of claim 1 , wherein:

at least some of the grooves of the plurality of grooves are on an apex of the extrados surface.

6. The gas liquid separator of claim 1 , wherein:

at least some of the grooves of the plurality of grooves are on the intrados surface.

7. The gas liquid separator of claim 1 , wherein:

the plurality of plates are free of straight sections in the main gas flow direction.

8. The gas liquid separator of claim 1 , wherein:

the extrados wing profile shaped camber of the at least one of the corrugations has a non-fixed radius.

9. A gas liquid separator for separating liquid droplets from a gas flowing generally in a main gas flow direction through the gas liquid separator, the gas liquid separator comprising:

a plurality of plates, mutually parallel and spaced apart to form a flow channel therebetween, each plate of the plurality of plates having a plurality of corrugations, wherein at least one of the corrugations comprises an intrados wing profile shaped camber followed by an extrados wing profile shaped camber, and wherein the plurality of plates are free of straight sections in the main gas flow direction and are free of sinusoidal curves;

stagnant zones that are created between a separation point, where a main gas flow detaches from a surface of each of the plurality of plates, and a reattachment point, where the main gas flow re-attaches to a surface of each of the plurality of plates; and

a plurality of grooves arranged in close association with one another and extending orthogonal to the main gas flow direction, the plurality of grooves being configured and positioned so as to increase energy of a turbulent boundary layer on the extrados wing profile shaped camber prior to the separation point; and

wherein the at least one of the corrugations includes an intrados surface and an extrados surface, the extrados surface defining an airfoil configuration.

10. A gas liquid separator for separating liquid droplets from a gas flowing generally in a main gas flow direction through the gas liquid separator, the gas liquid separator comprising:

a plurality of plates, mutually parallel and spaced apart to form a flow channel therebetween, each plate of the plurality of plates having a plurality of corrugations, wherein at least one of the corrugations comprises an intrados wing profile shaped camber followed by an extrados wing profile shaped camber, the extrados wing profile shaped camber having a radius that increases moving from a leading edge in a downstream direction of the main gas flow;

wherein the at least one corrugation includes an intrados surface and an extrados surface, the extrados surface defining an airfoil configuration;

wherein the shape of the extrados wing profile shaped camber is configured to trigger separation of the main flow at a separation point further along the corrugation than would occur if the corrugation had a fixed radius curve or sinusoidal curve.
