Welcome NAVIGATION Approach Daemons TEST-Code

Tutorial>Navigation and Page Layout

 

Launch TEST from the
locally installed copy
or
www.thermofluids.net
 
 
 
 
 
 
 
 

Registration is completely voluntary and is not required 
to access TEST

 

 a. Launching TEST: The TEST Home Page (Fig. 1) is accessed when you click on the index.html file of the locally installed copy of TEST, or access TEST on line at http://www.thermofluids.net. 

On the primary window, bring up the TEST Home Page. The complete list of mirror sites appear in the left  column below the TEST logo. Experiment with different servers until you locate the one that works best for you. Bookmark your favorite server. If are running a local copy of TEST from your hard disk, bookmark that location just like you bookmark any website. While running TEST locally, you will not need any Internet connection.

Registration simply means submitting your email address to receive occasional (once or twice a year) letters from the author about significant upgrades or changes, if any. It is a token of support for the TEST project rather than a required 

The URL www.prenhall.com/thermo serves as the gateway to a TEST-based textbook project currently underway.

The TEST Task Bar is a permanent switching station.
 
 
 
 
 
 
 
 

Three places to find solved problems.

 b. The TEST Task Bar: Located at the bottom of the primary window, the Task-Bar is a permanent launch pad for all the major components of TEST.  The components are displayed on the primary window, except for this Tutorial and  the Archive, which appear on a floating pop-up window to facilitate simultaneous view.

Three separate components of TEST carry solved examples, which can be a bit confusing. The examples in the Slide Show  introduce users to TEST solution through a comprehensive series of screen shots, visually. The solutions in the Tutorial> Daemons> Applications page contain detailed instructions with emphasis on daemon classification. The Archive contains fifteen different chapters of solved examples and TEST-Codes, organized in the traditional textbook style. As user contribution grow, it is very likely that you will find here the TEST-Code necessary to jump-start a solution for a problem you are trying to solve. Try all three and find out what works for you.

Systematic navigation 
starts at the Daemons page.
 

 

 c. The Daemons and the Systems Pages: Now let us check out a few pages. On the primary window, click the Daemons link. Figure 3  shows the image of the page that should appear on the primary window.

Fig. 3 Each TEST page, like this Daemon Page, has a similar layout.

 

All TEST pages have a consistent look and feel.
 

The Address Bar 
provides quick access to
all Ancestor Pages.
 
 
 
 

Every page, except for a 
leaf page, offers an exhaustive list of choices in a Simplification Table.

 

 There are several things that you notice in the layout of this page that is common to all TEST pages. The header consists of a title followed by an Address Bar with an unique hierarchical address of the page (Home.Daemons) and its iconic representation. The icons on the Address Bar are designed to remind the user of the series of assumptions made to get to that page and provide hot links to the ancestor pages. 

ASimplification Table describing all possible destination pages  is displayed below the header. During a problem solving session, you will read the description of each Child Page and decide on the most appropriate destination that best fits the problem at hand. The help icon, Page-Specific Help Appears in Bottom Frame , brings up page-specific Help Page and defines some of the key technical terms used in the table. You have to use the Back button of your browser to return to the table from the Help Page.

  Check out a few 
more  Pages.		 Click on the Systems icon to bring up the Home.Daemons. Systems  page (Fig. 4) on the primary window. Notice the similarities between the Systems page and the Daemons page (Figs. 3 and 4). The new Simplification Table offers only two choices for a system: Open or Closed . The governing balance equations and the corresponding schematics are shown below in Fig. 5. Continue to traverse down the TEST-tree and explore a few branches, Daemons. Systems. Open. SteadyState, for instance.

Macromedia Flash plug-in is required to view the animations.

Fig.6 Customized balance equations are also displayed on the
system pages.  Examples from Daemons.Systems and Daemons.Systems.Open pages. 

 

Navigation using the truth tables helps an user learn how the governing equations respond to simplifications unique to a problem.

 d. System Schematic and Governing Equations: As you continue to simplify a problem by making suitable assumptions using the  truth tables , the system schematics and the set of balance equations adjust to the newly imposed simplification. Figures 5 and 6, copied from the help pages of Daemons. Systems and Daemons.Systems.Open  pages, show that Wdot changes to Wdot_ext in the schematics as the  energy equation separates the flow work and lumps it into the mass flow terms through the use of the variable j (specific total enthalpy or flow energy). 

The progression of system schematic and governing equations from the generic form to a problem-specific form continues and culminates in their simplest form in a daemon. The system daemons displays the particular form of the mass, energy, entropy or exergy equation it solves in panels that are organized in layers. The daemons will be discussed in its own chapter in this Tutorial.

The TEST-Map bypasses the truth tables and takes an advanced user directly to the desired daemon page. 		 e. The TEST-Map: Advanced users, who can visualize the series of simplification that leads to a daemon, can use the Map (Fig. 7) to jump to a particular daemon page.

At any time when you click the Map link on the Task Bar, the tree structure (more on this on the Approach section) of TEST is displayed in an image map (see Fig. 7). Simply click on a node to visit that page (try it for the Daemons.Systems.Open page, for instance). 

 

What's next?		 f. The Daemon Page:  The leaf pages (pages without the need for a simplification table) of the TEST-tree is where the daemons reside. The goal of a successful navigation is to locate the right daemon for the job. Before we discuss the layout of the daemons, let us review  the TEST Approach   that leads to the right daemon.
