How to enter HRTI material properties parameters
Thread Content
Question: When selecting an economizer for HTRI 9, how can the property data for the hot side and cold side be entered? There are three options for the physical property input parameters: property tables, composition based, and property generator. Which one should be chosen? How to enter the detailed physical property parameters of the medium? Thank you. The physical property parameters for the hot side and cold side are as follows: Exhaust side (hot side): Absolute dry air: 168,000 kg/h; Absolute moisture content: 0.137 kg H2O/kg; Temperature: 78°C. Fresh air side (cold side): Absolute dry air: 116,000 kg/h; Absolute moisture content: 0.02 kg H2O/kg; Temperature: 30°C℃
In the HTRI software, to enter the property data for the hot side and the cold side, you can select the “composition based” option, and then input the detailed property parameters based on the specific components and proportions of the exhaust gas side and the fresh air side. In practice, you need to find the corresponding media input page in the software, and then enter the appropriate percentages and physical property values based on the actual composition of the medium. If your medium is a standard medium, you can also choose “Property Tables” to search for and select it directly. If the medium is special and cannot be entered using the first two methods, the “property generator” can be used to generate the required physical property data. Make sure all parameters are correct when entering. .
I learned it! :lol:lol:lol
I have a book that explains it in great detail. http://www.fishsting.com/down/book/hrqhtri.html
Here, two basic concepts are involved: 1. The use of three options: Property tables: for manually entering material property curves; Composition based: uses the built-in property packages, those from HTRI or VMG; generally used for single-component systems. Property generator: chosen when dealing with multi-component or aromatic systems, as it is used to simulate these components, requiring the input of the components and their proportions. 2. Input of moist air ； Enter the Air+H2O ratio using your own mass ratio. Definition criteria: operating pressure, operating temperature range. Additionally: These are all the basic functions of the HTRI software; if you are not familiar with them, it means there is still a long way to go before you can determine the structure of the economizer. Suggestion: Take a look at the built-in Sample cases to learn first, then proceed with practical application.
You can use a process simulation software such as Aspen Plus or HYSYS to calculate the material and heat balances, and then import those results into HTRI; this is the simplest approach, as it eliminates the need to enter parameters manually.
When I click on it, it takes me to your personal page. How do I download it? The right one wasn’t found
Copyright is strictly regulated these days; I definitely can’t put it somewhere for others to download for free! I’m just telling you that there is such a book, and it’s quite good.
