Lab-scale Experimentation and CFD Modeling of a Small Particle Heat Exchange Receiver

Lab and Field Scale Modeling of Near Miscible CO2 Injection in Different Porous Mediums

The main purpose of this investigation is to study the effect of near miscible CO2 injection in different porous mediums on both lab and field scales. This effect can be traced by the change of two-phase gas-oil relative permeability curves. In this work, the experiments have been performed on three rock types (i.e. sandstone, dolomite, and artificial fractured sandstone) based on an incrementa...

High-fidelity CFD modeling of particle-to-fluid heat transfer in packed bed reactors

The novel high-fidelity CFD model for packed bed reactors is validated in terms of Nu regarding particle-to-fluid heat transfer. The model is developed to take into consideration the flow of heat, mass and momentum through and around the particles each shaped without geometrical simplification. In the present approach, cylindrical shaped solid geometries are used to bridge particles in or near ...

Experimental and Computational Heat Losses for a Small Dish Receiver

Experimental and computed losses and reactor tube temperature profiles are presented for three ammonia receiver/reactor geometries operating on a 9 m dish concentrator. Preliminary analysis of receiver losses indicates that as the half cone angle of the receiver tube frustum reduces – from 17.5o to 7.5o to 3.7o – there is a shift from convection-dominated losses to radiation-dominated losses. T...

validation of a revised logical-mathematical intelligence scale and exploring its relationship with english language proficiency

نظریه هوش چندگانه قسمتهای متفاوت هوش بشری را مورد بررسی قرار می دهد که با شناخت آن شخص به درک بهتری از توانایی های خود میرسد و در نتیجه سعی در استفاده از آن جهت یادگیری بهتر میکند. همچنین با شناخت استعداد دانش آموزان، فرایند یادگیری بهتر میشود. هدف از انجام دادن این تحقیق بررسی رابطه بین هوش ریاضی و استعداد یادگیری زبان انگلیسی میباشد. برای انجام این تحقیق از پرسشنامه هوش ریاضی که توسط شیرر در ...
