    Recycling Heat Energy for Engines: Exploring Countercurrent Exchange

    I agree that each heat engine inside will only operate at carnot efficiency, but the system as a whole appears not to. I also agree with your second statement, heat energy is lost from the system hence the need for a heat source. The problem is that entropy is reduced. If you had the fluid...

    Recycling Heat Energy for Engines: Exploring Countercurrent Exchange

    Oxygen absorption is similar to heat absorption. Oxygen diffuses from places of high concentration to low concentration. Transfer is a result of a concentration gradient. russ_watters, Yes a Recuperator is essentially what the recycler is. I i don't think in combustion engines they can be...

    Recycling Heat Energy for Engines: Exploring Countercurrent Exchange

    It seems you are not considering, that heat energy is lost from the system, when heat energy passes through the heat engine. The biggest problem i have with what your saying is how you describe effciency. My understanding of efficiency is that it takes a cirtain amount of energy to create a...

    Recycling Heat Energy for Engines: Exploring Countercurrent Exchange

    "The energy used to heat the feedwater is usually derived from steam extracted between the stages of the steam turbine. Therefore, the steam that would be used to perform expansion work in the turbine (and therefore generate power) is not utilized for that purpose." wikipedia on feedwater heater...

    Recycling Heat Energy for Engines: Exploring Countercurrent Exchange

    I'm not getting you on this! After going through the heat engine the recycler heats the fluid and then it passes to the heat source to get even hotter. I don't get how if the fluid exits the same temp as the heat source, from the heat source you wouldn't need the recycler. when it exits the heat...

    Recycling Heat Energy for Engines: Exploring Countercurrent Exchange

    The recycler adds efficiency to the system by heating fluid closer to the heat souce temp than it would otherwise be without the recycler. As the fluid is already pre warmed it takes less energy to to warm the fluid to the temperature specified for it, in the heat source. It takes less...

    Recycling Heat Energy for Engines: Exploring Countercurrent Exchange

    At no point during the process do i see a deffience of the clausius statement occurring, nor is the exhaust heat hotter than the hot source. The heat source is the hottest thing in the system. Imagine a system that is very standard (different to the on depicted). fluid passes through a heat...

    Recycling Heat Energy for Engines: Exploring Countercurrent Exchange

    I'm not getting both, can you both elaborate? The intention of the exchanges is to use energy that is usually exhausted from the system into the sink, to lessen the amount of heat energy required to make the hot component of a heat a specific temperature without reducing the heat gradient. can...

    Recycling Heat Energy for Engines: Exploring Countercurrent Exchange

    When thinking about how everyday engines could be made to be more efficient . I remembered a biology lecture, where I was taught that the blood in the gills of a fish, move in the opposite direction of water flow when they swim, allowing them to absorb a higher level of oxygen from the water...
