Abstract: A plant for regasification of LNG includes a pump boosting LNG pressure, an LNG/coolant heat exchanger producing NG from LNG from the boosting pumps, and a closed coolant loop extending through the LNG/coolant heat exchanger and including a heat exchanger. The coolant from the heat exchanger is passed through the LNG heat exchanger as a gas and leaving in a condensed state to produce NG by thermal exchange. A heating medium is used within the heat exchanger to provide coolant in a gaseous state. An NG/coolant heat exchanger is arranged in connection with the LNG/coolant heat exchanger and is connected to the closed coolant loop. LNG is preheated within the LNG/coolant heat exchanger and NG is trim heated within the NG/coolant heat exchanger using liquid coolant from at least one heat exchanger.

Abstract: One or more embodiments of techniques or systems for shaped recess flow control are provided herein. A shaped recess or cavity can be formed on a surface associated with fluid flow. The shaped recess can be configured to create or induce fluid effects, temperature effects, or shedding effects that interact with a free stream or other structures. The shaped recess can be formed at an angle to a free stream flow and may be substantially “V” shaped. The shaped recess can be coupled with a cooling channel, for example. The shaped recess can be upstream or downstream from a cooling channel and aligned in a variety of manners. Due to the fluid effects, shedding effects, and temperature effects created by a shaped recess, lift-off or separation of cooling jets of cooling channels can be mitigated, thereby enhancing film cooling effectiveness.

Abstract: A thermal storage heat pump system transfers heat to a passenger compartment of a vehicle from at least one of a thermal storage device and ambient air. Heat from the thermal storage device is absorbed by a first coolant flowing through it, and is transferred to a refrigerant via a first heat exchanger. The heat is then transferred from the refrigerant to a second coolant via a second heat exchanger, and then from the second coolant to air flowing into the passenger compartment via a heater core. Heat from ambient air is absorbed by the refrigerant via a third heat exchanger. The heat source is determined by at least one of the thermal storage device temperature, ambient air temperature, and ambient air humidity. At start-up of the vehicle, heat transfer to the refrigerant and to the second coolant is controlled based on low-side and high-side pressure measurements of the refrigerant.

Abstract: A heat exchanger for transferring heat between two fluids consists of a shell surrounding at least two tube bundles attached at both ends to a tube header. Each of the tube bundles is constructed from a plurality of individual tubes that are twisted into identical helixes formed about a common helical axis. Because each individual tube is formed in the shape of a helix, rather than as a straight tube, thermal elongation of the individual tubes results in a considerably reduced axial force on the tube attachments and tube header. Use of multiple tube bundles wound with opposite twist direction improves spacing efficiency between tubes.
