Char

 

(Salvelinus), a genus of fish of the family Salmonidae, with two species: the Alpine char (S. alpinus) and S. leucomaenis. (According to some sources, there are four species.)

In lakes, chars develop habitat types, which are considered subspecies by some taxonomists and species by others. The char is found along the shores of Europe and northern Asia. Its body length is 35–65 cm (rarely, up to 88 cm), and its weight is 1–3 kg (sometimes up to 15 kg). A migratory fish, the char enters rivers for spawning from June to September and spawns in October-November of the sixth to seventh year of its life. The young go out to sea when they are two to four years old. S. leucomaenis inhabits the waters of the Far East, where the subspecies 5. alpinus malma (the Dolly Var-den) is also found. Although the meat of the char has excellent flavor, the fish has only slight commercial importance.

char

(programming)
/keir/ or /char/; rarely, /kar/ character. Especially used by C programmers, as "char" is C's typename for character data.

char

(CHARacter) In programming, the mnemonic for declaring a variable or array that holds alphanumeric characters. Pronounced "char" or "car," the C statement char OneChar; declares a single-byte variable named "OneChar," which holds one character. The declaration char InBuff[1000]; reserves a 1,000 byte array named "InBuff."

where: *--the equation is applicable when the charring rate is [less than or equal to] than the indicated specific value.
It is clear that the effective heat of combustion is not a constant; it is roughly 12 MJ/kg for the first part of the test, but increases to around 30 MJ/kg during the charring period at the end of the test (Babrauskas 2008).
The charring rates of wood increase as the heating time increases, with the exception of oak wood, the charring rate of which after 10 minutes of heating is smaller that after 5 minutes of heating.
The largest value of the correlation coefficient (R = 0.9597) was obtained when predicting the charring rate for aspen and the smallest value (R = 0.9240) was obtained when predicting the charring rate for pine.

Charring is faster when the cross-section is smaller, due to two-dimensional heat flux within the member.
Coefficient [k.sub.n] converts the irregular charring depth into a notional charring depth, see Figure 3.
Tests were performed over 30-60 minutes until 60 mm charring of timber was reached on the narrow side.
Minimum and maximum values of densities were found and according to value of density, notional charring was taken into account.
The difference in charring rate as a result of changing one property or factor varies also, as can be seen in Table 4.
Although the heat-resistant glass wool exhibits thermal expansion at joints, the greater charring depth is measured at the positions of joints in the insulation.
That makes the results comparable and the difference in measured charring rates is mostly caused by density and size effect of cross-section.
